Descripción

This is a simple moisture sensor can be used to test the moisture of soil, when the soil water shortage, module output a high level, and output low level.

Use this sensor making one automatic watering the flowers device, make your garden plants need not to management.

  • Sensitivity adjustable (shown in blue digital potentiometer control)
  • Working voltage of 3.3 V - 5 V
  • Module double output mode, digital output is simple, analog output more accurate.
  • Has fixed bolt hole, convenient installation
  • Small board PCB size: 3 cm * 1.6 cm
  • The power indicator light (red) and digital switch output light (green)
  • Comparator the LM393 chip, work stability

Interface specifications (4 wire)

  1. VCC external 3.3 V - 5 V
  2. GND external GND
  3. DO digital output interface (0 and 1)
  4. AO analog output interface

Instructions

  • Soil humidity module to the environmental humidity is the most sensitive, generally used to detect soil moisture.
  • Module in soil moisture can not reach the setting threshold, DO mouth output high level, when soil moisture more than setting threshold, module D0 output low level;
  • Digital output D0 can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect the high and low level, thus to detect soil moisture;
  • Digital output DO can directly drive the relay module, buzzer module, which can form a soil humidity alarm equipment;
  • Analog output AO and AD module can be linked together, through the AD conversion, can get soil moisture more accurate numerical;

Four shipping list

  • As shown in figure soil moisture detection module finished plate a (including test plate and soil moisture probe)
  • 1 x dupont 5 line.
