Makers might be interested to know that Adafruit is now stocking a new STEMMA capacitive soil moisture sensor which provides superior enhancements when compared with resistive style soil moisture ...

A frequent beginner project involves measuring soil moisture levels by measuring its resistance with a couple of electrodes. These electrodes are available ready-made as PCBs, but suffer badly from ...

Soil moisture profile measurements are an integral component of water balance estimation networks, especially in thick vadose zones and fine-grained soil environments. At field sites with silty and ...

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...

Recently, I got a Chirp! plant-watering alarm for evaluation from wemakethings. Chirp, designed to be run on a 3-V CR2032 lithium coin cell, is an electronic plant-watering alarm. You put it into the ...

Continuous and accurate sensing of water content in soil is an essential and useful measure in the agriculture industry. Traditional sensors developed to perform this task suffer from limited lifetime ...
