What is Soil Moisture Sensor Module?
The soil moisture sensor module is used to detect soil moisture. It measures the volume content of water in the soil and provides us with water content. The module has digital and analog outputs as well as potentiometers for adjusting the threshold level. The humidity sensor module consists of humidity sensor, resistor, capacitor, potentiometer, comparator LM393 IC, power supply and status LED.
Pin configuration of Soil Moisture sensor module
|VCC||The Vcc pin powers the module, typically with +5V|
|GND||Power Supply Ground|
|DO||Digital Out Pin for Digital Output.|
|AO||Analog Out Pin for Analog Output|
