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

  1. 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 exceeds the 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, and thus to detectsoil moisture;
  4. Small plates digital output DO shop relay module can directly drive the buzzer module, and which can form a soil moisture alarm equipment;
  5. Small plates analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
