DRAGINO LoRaWAN Wireless Rain Gauge Weather Monitoring Sensor

What Is the DRAGINO LoRaWAN Wireless Rain Gauge Weather Monitoring Sensor (WSS-21)?

The Dragino WSS-21 is a LoRaWAN wireless rain gauge designed to measure rainfall and transmit rainfall data over a long-range, low-power LoRaWAN network.

The device is designed for outdoor weather and environmental monitoring applications where rainfall data needs to be collected remotely. It can be integrated into LoRaWAN-based weather monitoring systems and connected to a compatible LoRaWAN gateway for data transmission to an IoT platform or network server.

The WSS-21 uses a tipping-bucket rain gauge mechanism to measure accumulated rainfall. As rainwater enters the collector, it fills a calibrated tipping bucket. When the bucket reaches its calibrated capacity, it tips and generates a measurement pulse. The system counts these tipping events and converts them into rainfall data.

The collected information can then be transmitted wirelessly using LoRaWAN, enabling users to monitor rainfall remotely without requiring a wired communication connection between the rain gauge and the monitoring platform.

How Does the WSS-21 Work?

• Rainwater enters the collector
  Rain falls into the rain gauge's collection funnel.
• Water is directed into the tipping bucket
  The collected rainwater flows into a calibrated tipping mechanism.
• The bucket tips when a set volume is reached
  Once the bucket reaches its calibrated capacity, it tips and empties the collected water.
• A measurement event is generated
  Each tipping action represents a known quantity of rainfall.
• The device calculates rainfall data
  The sensor counts tipping events and determines rainfall measurements based on the calibrated tipping volume.
• Data is transmitted through LoRaWAN
  The WSS-21 sends rainfall data wirelessly to a LoRaWAN gateway.
• The gateway forwards the data
  The gateway transfers the information to a LoRaWAN network server or IoT platform.
• Users monitor rainfall remotely
  Rainfall data can be viewed, stored, analyzed, and integrated with weather or agricultural monitoring systems.
