Soil Moisture Sensor Module Introduction

The soil moisture sensor module is used to detect soil moisture.

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.
