Soil Moisture Sensor Module

Description

This is very simple and easy to use digital/analog soil moisture sensor. By simply inserting the sensor in the soil and it could measure moisture or water level content in it. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil. 

The sensor can be control by a potentiometer to set the desired moisture threshold. When the moisture is increased than the set threshold, the digital output goes high and an LED indicates the output. When the moisture level in the soil is lower than the set threshold, the output remains low. The digital output can be connected to a micro controller to sense the moisture level. The module also outputs an analog output which can be connected to the ADC of a micro controller to get the exact moisture level in the soil.

This sensor is great for making water gardening projects, water sensing,and various different innovative applications
