Monitoring Australian Farms with Dragino LoRaWAN for Soil Water and Pump Insights
A paddock can look fine from the ute and still be telling a very different story underground. Soil moisture may be falling faster than expected, a pump may be cycling at the wrong time, or pressure may be dropping at the far end of an irrigation line. By the time the problem is visible, water, power, crop health, and labour may already have been wasted.
That is where Dragino LoRaWAN technology fits well on Australian farms. It gives growers a practical way to collect field data from distant tanks, bores, pumps, irrigation lines, and soil probes without running cable across the property or relying on mobile coverage at every point.
A LoRaWAN setup can bring readings from many distributed assets back to a single gateway, then send that information to a dashboard, app, or farm management platform. For mixed farms, orchards, vineyards, broadacre irrigation, and grazing properties, that can turn scattered assets into one connected monitoring system.
Why LoRaWAN suits Australian farm monitoring
Australian farms often cover large areas, and the assets that matter are rarely close together. A soil probe may sit in one block, a tank on a ridge, a pump beside a bore, and a pressure sensor near the end of a mainline. Checking each point manually takes time, fuel, and attention that could be used elsewhere.
LoRaWAN, short for Long Range Wide Area Network, is designed for low-power devices that send small packets of data across long distances. That makes it a strong fit for farm telemetry, where sensors do not need to stream video or large files. They only need to transmit clear readings at set intervals.
A typical farm system has three layers:
Layer | What it does | Farm example |
Sensors and nodes | Measure conditions and send readings by LoRaWAN | Soil moisture probe, tank level sensor, pump status input |
Gateway | Receives LoRaWAN messages from many devices | One gateway on a shed, mast, hill, or homestead |
Network server and dashboard | Stores, displays, and alerts on the data | Graphs, alarms, irrigation reports, pump runtime logs |
The gateway is the collection point. It can receive messages from many nodes across the farm, then pass them on using Ethernet, Wi-Fi, 4G, or another backhaul connection. That means individual sensors do not each need a SIM card or mains-powered internet connection.
The result is a simpler field network. Sensors stay near the thing they measure, and the gateway sits where it has the best coverage and backhaul.
What Dragino devices can monitor across the property
Dragino makes LoRaWAN equipment used in many monitoring setups, including gateways, sensor nodes, and interface devices that connect to external probes or industrial signals. On farms, the strength is not one single reading. It is the ability to combine soil, water, weather, and equipment data into a shared view.
Soil moisture shows what roots can access
Soil moisture monitoring is often the starting point for irrigation decisions. A probe placed in the crop root zone can show whether water is available where plants need it, not just whether the surface looks damp.
Good soil moisture data can help answer practical questions:
Has irrigation reached the active root zone?
Is water draining below the useful depth?
Is one block drying faster than another?
Can the next irrigation run wait?
Is rainfall enough to refill the profile?
For Australian conditions, where water allocations, pumping costs, and dry spells can all bite, these readings are valuable. They support better timing, not guesswork.
Soil temperature helps put moisture data in context
Soil temperature matters because plant growth, germination, root activity, and nutrient processes all respond to temperature. Moisture readings on their own are useful, but they become more meaningful when paired with soil temperature.
For example, cool soil may slow crop water use even when the profile is wet. Warm soil and windy weather may increase demand quickly. By tracking soil temperature beside soil moisture, a farm can better understand why water use changes from week to week.
Electrical conductivity can flag salts and fertiliser movement
Electrical conductivity, often shortened to EC, measures how well soil water conducts electricity. In farm monitoring, it can give clues about salinity, fertiliser concentration, and changes in the soil solution.
EC data does not replace proper soil testing, but it can show trends. A rising EC pattern may suggest salts are concentrating as the soil dries, or that nutrients are moving through the profile after fertigation. In irrigated horticulture, vineyards, greenhouses, and some broadacre systems, this extra layer can help identify stress before it shows in the crop.
The key is trend tracking. One EC number in isolation has limited value. A season of readings, matched with irrigation and weather, tells a clearer story.
Water storage, flow, pumps, and pressure belong in the same system
Soil data explains crop demand. Water infrastructure data explains whether the farm can meet that demand. Dragino LoRaWAN devices can be used as part of systems that track tank level, water flow, pump status, and irrigation pressure, bringing the supply side into the same picture.
Tank level monitoring reduces wasted trips
Tank checks are simple, but they are easy to miss when the tank is far from the house, shed, or main work area. A LoRaWAN tank level sensor can report how much water is available and alert when the level drops below a set point.
This is useful for:
Stock water tanks in remote paddocks
Header tanks feeding irrigation zones
Rainwater tanks at outstations
Chemical or fertigation tanks where compatible sensors are used
Temporary storage used during seasonal operations
The value is not just avoiding an empty tank. It is knowing whether the tank is falling faster than normal, refilling as expected, or failing to respond when a pump should be running.
Water flow data confirms what actually moved
Flow meters can show whether water is moving through a line and how much has passed. When connected through a LoRaWAN pulse counter or suitable input device, that data can be sent back to the gateway for logging.
Flow monitoring can help detect:
Blocked filters
Broken pipes
Unexpected night flow
A zone that failed to open
More water use than planned
Less flow than expected from a pump
A scheduled irrigation event should leave a trace in the flow record. If the pump ran but the flow stayed low, the issue may be a valve, blockage, airlock, or pump performance problem.
Pump status shows runtime and faults
Many farm pumps still get checked by sound, sight, or a quick visit. That works until the pump is several kilometres away or starts at night. LoRaWAN monitoring can track whether a pump is on or off, often by reading a dry contact, relay, current sensor, or controller output.
Pump status data can show:
When the pump started and stopped
How long it ran
Whether it ran outside its normal schedule
Whether it failed to start when called
Whether it short-cycled due to a pressure or control issue
This is especially useful when paired with tank, pressure, and flow readings. A pump-on signal with no pressure rise tells a different story from a pump-off signal with falling tank level.
Irrigation pressure protects the far end of the system
Pressure readings help confirm that irrigation is operating within the intended range. Low pressure can lead to poor sprinkler performance, uneven application, or failed drip zones. High pressure can damage fittings, increase leaks, and waste power.
A pressure sensor at the pump may not tell the full story. Many farms benefit from pressure monitoring near critical points, such as:
The end of a mainline
A distant irrigation block
A filter station
A pivot feed point
A drip irrigation manifold
When pressure data is visible with flow and pump status, faults become easier to narrow down. A sudden pressure drop may point to a burst pipe. High pressure with low flow may suggest a blockage or closed valve.
Weather data completes the operating picture
Weather stations and local climate sensors are a natural fit for LoRaWAN. A farm can collect readings such as rainfall, air temperature, humidity, wind speed, wind direction, solar radiation, or leaf wetness, depending on the sensors used.
Local weather conditions matter because the nearest public weather station may not match the farm. It may sit many kilometres away, at a different elevation, or in a different microclimate.
On-farm weather data can support:
Irrigation scheduling after rainfall
Spray planning based on wind and humidity
Frost awareness in vulnerable blocks
Heat stress monitoring for crops and livestock
Disease risk models where suitable software is used
Comparing water use against evapotranspiration estimates
Weather data also helps explain the other readings. If soil moisture drops quickly during a hot, windy week, that makes sense. If it drops quickly after cool, still days, it may point to drainage, leakage, or sensor placement.
How one gateway can collect data from many farm assets
The main advantage of long-range LoRaWAN is simple: many low-power devices can send readings to one gateway across a wide area.
Each sensor node has a LoRaWAN radio. At planned intervals, it wakes, takes or receives a measurement, transmits a small message, then goes back to low-power mode. The gateway listens for those messages. It does not need to be cabled to each sensor, and it can hear many devices if the radio path is suitable.
The gateway then forwards the data to a server or platform. From there, readings can appear in dashboards, graphs, maps, alerts, or downloaded reports.
A farm might have one gateway receiving data from:
Soil probes in several irrigation blocks
A weather station near the crop
Tank level sensors on remote storages
Flow meters at pump sheds
Pressure sensors at the far end of lines
Pump status inputs from bores or transfer pumps
For best results, the gateway should be placed high and clear where possible. Farm sheds, silos, masts, ridgelines, and homesteads can all work, depending on terrain and backhaul. Hills, trees, metal sheds, and valleys can affect radio performance, so a site check is useful before final placement.
Some larger or more complex farms may use more than one gateway. That can improve coverage across broken country, separate enterprises, or distant blocks. The system can still bring the data into one platform.
Power options for sites without mains electricity
Many of the places that need monitoring are the same places that lack mains power. A tank in a remote paddock, a bore on the back boundary, or a pressure point near the end of a line may be nowhere near a power outlet.
LoRaWAN suits these locations because field devices are designed to send small amounts of data and sleep between transmissions. That can make battery operation practical for many sensors, especially where readings are sent every few minutes, hourly, or a few times per day rather than every second.
Battery-powered sensors suit low-touch monitoring
Battery-powered units reduce installation work. There is no trenching, conduit, or local power supply to arrange. They are useful for:
Soil probes
Tank level sensors
Gate or contact status inputs
Weather sensors with low power demand
Remote pressure or flow monitoring where the signal type allows it
Battery life depends on the device, battery size, sensor type, reporting interval, signal strength, and weather exposure. A sensor that transmits often will use more power than one that reports less frequently. Poor signal can also shorten life if the device has to work harder to communicate.
The best practice is to choose reporting intervals that match the decision. A tank level may not need updates every minute. Pump status may need faster reporting than soil temperature. Fit the interval to the job.
Solar-powered options support higher demand sites
Solar power becomes useful when the device draws more current, reports often, powers external sensors, or sits at a site that also needs a controller or gateway. A small solar panel and battery can keep equipment running where mains power is not available.
Solar-powered monitoring is common for:
Remote gateways
Weather stations
Pump monitoring panels
Flow and pressure stations
Sites with several sensors in one location
Areas where frequent reporting is needed
The solar system should match the load and local conditions. In southern Australia, winter light can be limited. In northern regions, heat can affect battery life. Good mounting, correct panel angle, shade avoidance, and weatherproof enclosures all matter.
Turning readings into better farm decisions
Data only helps when it changes decisions. A good Dragino LoRaWAN farm setup should make routine questions easier to answer.
Is the soil wet enough to delay irrigation?
Did yesterday’s irrigation reach the deeper probe?
Is the tank refilling overnight?
Did the pump run when the controller called it?
Is pressure strong enough at the end of the line?
Did a rainfall event change the irrigation plan?
The most useful systems combine measurements rather than treating each sensor as a separate gadget. For example, a pump may show as running, but flow data shows little movement and pressure stays low. That points towards a suction, blockage, impeller, valve, or pipe problem. If the pump is off and tank level falls, the issue may sit elsewhere.
Alerts can also reduce response time. A low tank alert, pressure drop, pump fail signal, or unexpected flow after hours can prompt a quick check before the problem grows. On large properties, that early warning can save hours of travel and reduce the risk of stock or crop stress.
Historical data has value too. Over a season, the records can show which blocks used more water, how fast tanks recovered, where pressure problems repeated, and how weather changed irrigation demand. That makes planning easier for the next crop, season, or infrastructure upgrade.
Practical setup tips before installing sensors
A reliable monitoring system starts with clear goals. The best sensor layout is shaped by the questions the farm needs answered.
Before installation, work through these points:
Map the assets
Mark tanks, pumps, bores, valves, irrigation blocks, high points, low points, and likely gateway locations.
Choose the key readings
Start with the data that will change decisions, such as soil moisture, tank level, pump status, flow, or pressure.
Check radio paths
Place gateways high where practical, and account for hills, sheds, tree lines, and long distances.
Protect equipment
Use suitable enclosures, cable protection, strain relief, and mounting hardware for heat, dust, rain, livestock, and machinery.
Set useful alert thresholds
Avoid too many alerts. Focus on events that need action, such as low tank level, no flow, low pressure, or failed pump start.
Review the data after installation
Make sure readings match real conditions. A sensor in the wrong place can give neat graphs and poor guidance.
Dragino LoRaWAN equipment gives Australian farms a practical way to connect soil, water, weather, and pump information across distance. The real value comes from designing the system around decisions, not just collecting numbers.
When soil moisture, soil temperature, EC, weather, tank level, water flow, pump status, and irrigation pressure feed into one view, the farm becomes easier to read. Problems show earlier. Irrigation timing becomes clearer. Remote assets take fewer blind trips to check.
For many rural sites, battery and solar-powered options make that possible even where mains power is unavailable. Start with the assets that cause the most uncertainty, place the gateway well, and build a monitoring system that helps every reading earn its place.
