This is a simple and easy moisture sensor that can be used for the detection of soil moisture. The module outputs a high level, when soil moisture is deficit, the output is low level. Using the sensor produces a watering device automatically, let you don't choose and employ persons to manage the plants in the garden.
Soil Moisture Sensor Features:
The working voltage of 3.3 V to 5 V.
Simple digital output, g v directly by single chip microcomputer.
The sensitivity is adjustable using digital potentiometer (blue).
A fixed bolt hole, convenient installation.
The power indicator light (red) and digital switch output indicator light (green).
