Unlike the normal module, this sensor does not have an adjustable switching contact, it works analog and thus displays the exact moisture values in real time. Since the sensor works capacitively, this sensor does not contaminate the substrate even after a long period of use. This also results in a high durability.
Supports 3-pin gravity sensor interface
Analog Output
VCC:3.3V-5V

dimension:22 x 97 x 9mm with a 3-cable cable of 190mm
The analog output AO can be connected to the AD module, and through AD conversion, it can obtain a more accurate value of soil humidity. The analog output AO can be connected to the AD module, through the AD conversion, you can get a more accurate value of soil humidity
