Soil Moisture Sensor Module

This is a summary of the moisture sensor that can be used to detect moisture in the soil, when the soil is dry, the module outputs a high level, whereas the output is low. Using this sensor makes an automatic watering system so that your garden plants need people to manage them.

Adjustable sensitivity ( shown in blue digital potentiometer adjustment ) Operating Voltage 3.3V-5VModule Dual Output mode, a simple digital output, analog output more accurate.  

With fixed bolt hole for easy installation
