Extensive tests of watermark-based devices with soil temperature have started!

We are starting extensive tests of watermark-based device with a soil temperature sensor which allows for centibar conversion at the device itself. 2 variants will be tested: a 1-watermark and a 2-watermark device. With 2 watermarks, water movement in the soil can be better determined. The objectives are to determine the best configuration tradeoff in terms of cost vs accuracy with the possibility of have advanced calibration procedures to increase the accuracy of measured data.

The watermark-based soil device sensor will be compared to the lower cost capacitive soil device sensor.
