The soil moisture sensor consists of 2 components: the PCB circuit containing the comparator and the earthing part. The latter connects to the circuit and further, the connection is made with the circuit.
The sensor is ideal for innovative electronic projects, such as a device that regularly dries plants, depending on the soil moisture.
Adjust the soil moisture control threshold by potentiometer, can automatically water the vegetable garden, automatically garden, control the soil moisture of the family flower pot, various electronic games, electronic building blocks, arduino design.
1. Using the high-quality soil sensor produced by our company to test soil moisture, the surface is treated with nickel plating, and the wide sensing area can improve the conductivity, preventing the problem of easy rusting in contact with the soil, and prolong service life;
2. The product can control the moisture of the soil in a wide range, and the corresponding threshold is controlled by the potentiometer. When the humidity is lower than the set value, the DO output is high, and when it is higher than the set value, the DO output is low;
3. Compare The device adopts LM393 chip and works stably.
4. Working voltage is 3.3V-5V.
5. Fixed bolt hole is provided for easy installation.
6.PCB size: 3.2cm * 1.4m
Wiring description (3-wire system)
1. 3.3V-5V external VCC
2. GND External GND
3. DO Small-plate digital output interface (0 and 1)
1. The sensor is suitable for soil moisture detection;
2. The blue potentiometer in the module is used for threshold adjustment of soil moisture. adjusting the clock, will control the humidity, the smaller the counterclockwise;
3. the digital output D0 can be directly connected to the microcontroller, the microcontroller is detected by the high-low, thus detecting soil moisture;
