By adjusting potentiometer control soil moisture threshold, it can automatically garden, automatic watering garden, household pots of soil moisture control, electronic games, electronic building blocks, arduino compatible design.
1. The use of soil sensors duced by our company to do testing soil moisture, the surface nickel plated, induction area widened, can im ve conductivity, to prevent contact with the soil rust blems and long life;
2. When the duct can control a wide range of soil moisture, adjust the corresponding threshold control potentiometer, the humidity is below the set value, DO output high, higher than the set value, DO output low;
3. comparators LM393 chip, stable
4. Working voltage 3.3V-5V
5. A fixed bolt hole for easy installation
6.PCB Size: 3.2cm * 1.4m
1 VCC 3.3V-5V external
2 GND External GND
3 DO small board digital output interface?0 and 1?
1. The sensors are suitable for soil moisture detection;
2. The modules in the blue potentiometer is a threshold for soil moisture adjustment clockwise adjustment will control the humidity, the smaller the counter-clockwise;
3. D0 digital output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting soil moisture;
