Description:

A low cost soil moisture sensor module designed to be used with microcontroller development boards. The module consist of two parts: A nickel plated PCB probe that is inserted into the soil, and a module which provides an interface to the microcontroller.


The sensor has both digital and analogue outputs:

The digital output will remain low when the soil moisture is above a set threshold level (set by on-board potentiometer). When the soil moisture content drops below this threshold level the output will go high.

The analogue output has a voltage ranging (approximately) between 0 and 5V when powered from a 5V supply. This output varies depending on soils moisture content. The output is suitable for connection to a microcontrollers analogue input pin.


Interface Pinout:

AO.......Analogue output
DO.......Digital output
GND.....0V
VCC.....3.3-5V


Specification:

Comparator uses LM393 device
Working voltage: 3.3V-5V
Screw hole for easy installation

Schematic:
