Remotely Monitoring Soil Moisture and Soil Temperature with Valarm Tools Cloud

Valarm Tools Cloud Soil Moisture Sensors Decagon GS3 Soils Temperature Moistures Sensor 1This is a Decagon GS3 soil moisture sensor. It measures soil moisture and soil temperature. In the field, you’ll bury the soil moisture sensor in the area of the soil that you need to monitor.

The Decagon GS3 connects to Valarm Tools Cloud via sensor hubs connected to Yoctopuce Serial sensor (UART TTL) adapters, like you see in the picture.

The white wire from the GS3 connects to the PWR terminal in the green connection block on the serial sensor adapter.

The Red wire connects to RD / Receive Data. And the silver ground wire connects to the ground port.

Valarm Tools Cloud Industrial IoT Remote Monitoring Sensor Telemetry Yoctopuce Serial Sensor Adapter Soil Moisture Sensor Decagon GS3 Real Time IIoT ApplicationsThe Decagon GS3 soil moisture sensor reports 3 parameter values for each reading. You can map these values to any field / column, like User1, User2, User3, on

The 1st sensor parameter value is Dielectric. The 2nd parameter is temperature in Celsius. The 3rd parameter is Electrical conductivity in uS/cm.

You can use this script .job file (remember to change the file type to .job) with Yocto-Serial sensor adapters to automatically ask the soil moisture sensor for its latest values at regular intervals.
