Soil Hygrometer Detection Moisture Sensor

product description:
1. The high-quality soil sensor is used to detect the soil moisture. The surface is nickel plated and has a widened sensing area, which can improve the electrical conductivity, prevent the problem of easy rust and prolong the service life;
2. The product can control the humidity of the soil in a wide range. The potentiometer adjusts and controls the corresponding threshold. When the humidity is lower than the set value, DO outputs a high level, and when it is higher than the set value, DO outputs a low level;
3. Comparator uses LM393 chip, stable operation
4. Working voltage 3.3V-5V
5. With fixing bolt holes for easy installation
6. PCB size: 3.2cm * 1.4m
Wiring instructions (3-wire system)
1 VCC external 3.3V-5V
2 GND External GND
3 DO small board digital output interface (0 and 1)
Module instructions:
1. The sensor is suitable for soil moisture detection;
2. The blue potentiometer in the module is used to adjust the threshold value of soil humidity. Adjust it clockwise, the greater the controlled humidity, the smaller it will be counterclockwise;
3. The digital output D0 can be directly connected to the single chip microcomputer, and the high and low levels are detected by the single chip microcomputer, thereby detecting the soil moisture;
