  • 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 without people to manage.
  • Sensitivity adjustable the blue digital potentiometer adjustment (Figure)
  • Operating voltage 3.3V-5V
  • Module dual output mode, digital output, analog output more accurate.
  • With fixed bolt hole for easy installation
  • PCB size: 3cm * 1.6cm
  • Power indicator (red) and digital switching output indicator (green)
  • Comparator LM393 chip, stable
  • Interface Description (4-wire)
  • VCC: .3 V-5V
  • GND: GND
  • DO: digital output interface (0 and 1)
  • AO: Analog Output Interface

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 to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low;
  • The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture;
  • The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment;
  • Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture
