Description
How often have you watered your plants and worried that you might be overdoing it? With this simple soil moisture sensor, those concerns are a thing of the past! This two-part sensor is easy to use. Two exposed electrodes are inserted into the soil and send moisture information through two connected wires. The more water in the soil, the better the results.
The two parts are connected using the included JST-SH 2-pin cable. The sensor utilizes the differential comparator LM393. The output signal can be either digital (HIGH/LOW) or analog (0V - VCC). The main advantage of this board is that it provides both digital and analog outputs. By adjusting the potentiometer on the board, you can obtain the digital signal within the sensitivity range set by the potentiometer, while the sensor continuously provides the analog output at all times.
