How many times have you watered your plants and feared you’re overdoing it? With the simple soil humidity sensor, those worries are a thing of the past! This two-part sensor is straightforward to use. The two exposed prongs go into the soil and send the humidity information to the sensor via the connected wire. The more water is in the ground, the better the results will be.

The main benefit of this board is ability to give analog and digital output. By setting the potentiometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.
