Product characteristics
 
1. Using high-quality soil sensor to detect soil moisture, and using nickel plating to treat the surface has a wider sensing area, which can improve the conductivity, prevent contact with soil rust and prolong the service life;
2. The product can control the humidity of the soil in a wide range, and adjust and control the corresponding threshold value through the potentiometer. When the humidity is lower than the set value, the do output is high level, and when it is higher than the set value, the do output is low level;
3 comparator adopts LM393 chip, which works stably
4. Working voltage 3.3v-5v
5. Fixed bolt holes are provided for easy installation
6. PCB size: 3.2cm * 1.4m

 Soil Humidity Sensor Module Land Hygrometer Modular Test Component
 
Wiring instructions
1. VCC external connection 3.3v-5v
2. GND external GND
3. Do small board digital output interface (0 and 1)
4. Ao small board voltage analog output
 
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 moisture. The higher the controlled humidity is, the smaller the anti clockwise is;
3. The digital output d0 can be directly connected to the single-chip microcomputer, through which the high and low level can be detected, thus the soil moisture can be detected;
4. The analog output Ao of small plate can be connected with AD module. Through AD conversion, more accurate value of soil moisture can be obtained
