Detailed Description:

This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module outputs a high level, and vice versaoutput low.

Use this sensor produced an automatic plant waterer device, so that the plants in your garden without people to manage.

Adjustable sensitivity adjust the digital potentiometer (shown in blue);
Operating voltage 3.3V-5V;
Module dual output mode, digital output, analog output more accurate;
A fixed bolt hole for easy installation;
Small plates PCB size: 3cm * 1.6cm;
Power indicator (red) and digital switching output indicator (green);
Using LM393 comparator chip, stable

Two small plates Interface Description (4-wire):

VCC external 3.3V-5V
GND external GND
DO-board digital output interface (0 and 1)
AO-board analog output interface

Three instructions for use

Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil;
Module in the soil humidity less than a set threshold value when the DO port output high, when the when soil humidity exceeds the threshold value is set, the module D0 output low;
Small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and thus to detectsoil moisture;
Small plates digital output DO shop relay module can directly drive the buzzer module, and which can form a soil moisture alarm equipment;
Small plates analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
