LoRaWAN Triple Temperature Sensor – 3× DS18B20 Waterproof Probes

The D23-LB Battery-Powered LoRaWAN Triple Temperature Sensor is built for applications where three independent temperature points must be monitored accurately over long distances. Designed for agriculture, HVAC, environmental monitoring, industrial processes, refrigeration, and smart building systems, it offers exceptional versatility and reliability.

The device includes three separate DS18B20 stainless-steel digital sensors, each capable of measuring –55°C to +125°C with ±0.5°C typical accuracy. This allows you to monitor multiple zones or compare temperatures such as:

• Inlet / midpoint / outlet pipe temperatures

• Three compost layers (core, mid, outer)

• Soil temperature at three depths

• Triple-zone fridges, freezers, or cool rooms

• Ambient, surface, and fluid temperature

• Three water tanks or three sections of a pipeline

The sensor uses LoRaWAN Class A for long-range, ultra-low-power data transmission and integrates seamlessly with AU915/AS923 networks including ProSight, TTN, TagoIO, ChirpStack, and private gateways.

A durable IP66 enclosure protects the electronics against dust, rain, and harsh outdoor environments. Powered by an 8500mAh Li-SOCl₂ industrial battery, the D23-LB provides up to 5 years of continuous use depending on reporting frequency.

Additional features include temperature alarms, BLE phone configuration, datalogging (stores readings offline until the network is available), and OTA firmware upgrades.

All ProSense LoRaWAN hardware — including the D23-LB — works seamlessly with ProSight Software, delivering dashboards, alerts, trend analysis, and compliance-ready reporting.
Advanced users can also integrate the sensor into custom IoT and SCADA platforms using standard LoRaWAN payloads.

ProSense stocks this model in Australia, with fast delivery and full local support.
