Remotely Monitoring Soil Moisture and Soil Temperature with Valarm Tools Cloud
This 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 a sensor hub connected to a Yoctopuce Serial sensor (UART TTL) adapter, which 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.
The 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 Valarm Tools Cloud – http://tools.valarm.net.
The 1st sensor parameter value is Dielectric. The 2nd parameter is temperature in C. 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 latest sensor for its latest values at regular intervals.
In the photo you see an example of a serial sensor adapter inside a weatherproof Valarm remote monitoring box. The Decagon GS3 soil moisture sensor enters the box through a cable gland and attaches to the serial sensor adapter as detailed above.
