This WaterMe app measures moisture in soil (or any other medium) using a resistive soil moisture sensor or a capacitive soil moisture sensor. When the moisture falls below an adjustable threshold level. a control signal is sent to a Mosfet Output Module which connects power to a 3-6v mini-pump. When the moisture level rises to above the threshold level, the …
