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 versa output low.Use this sensor produced an automatic plant waterer device, so that the plants in your garden withoutpeople to manage.
2 adjustable sensitivity adjust the digital potentiometer (shown in blue)
4 Operating voltage 3.3V-5V
5 module dual output mode, digital output, analog output more accurate.
A fixed bolt hole for easy installation
7 small plates PCB size: 3cm * 1.6cm
8 power indicator (red) and digital switching output indicator (green)
9 using LM393 comparator chip, stable

Two small plates Interface Description (4-wire)
1 VCC external 3.3V-5V
2 GND external GND
3 DO-board digital output interface (0 and 1)
4 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.

2 module in the soil humidity less than a set threshold value when the DO port output high, when the when soil humidity exceedsthe threshold value is set, the module D0 output low;

3 small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, andthus to detect soil moisture;

4 small plates digital output DO shop relay module can directly drive the buzzer module, and which can form a soil moisturealarm equipment;

5 small plates analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture;
