חיישן לחות אדמה

תיאור

By adjusting the soil moisture control threshold with a potentiometer, you can automatically water vegetable gardens, gardens, control soil moisture in home flower pots, various electronic games, electronic building blocks, Arduin design, etc.
Product introduction:
1. Use the high-quality soil sensor produced by our company to detect soil moisture. The surface is nickel-plated and has a widened sensing area, which can improve the conductive performance, prevent the problem of easy rusting when in contact with the soil, and extend the service life;
2. The product can control the humidity of the soil in a wide range. The corresponding threshold is controlled by adjusting the potentiometer. When the humidity is lower than the set value, the DO output is high level. When the humidity is higher than the set value, the DO output is low level.
3. Comparison The device uses LM393 chip and works stably
4. Working voltage 3.3V-5V
5. Equipped 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 usage instructions:
1. The sensor is suitable for soil moisture detection;
2. The blue potentiometer in the module is used for threshold adjustment of soil moisture. Clockwise adjustment, the controlled humidity will be larger and counterclockwise;
3. The digital output D0 can be directly connected to the microcontroller, and the high and low levels are detected through the microcontroller to detect soil moisture;
delivery list:
module and soil sensor One set, 2 pieces of 20cm long Dupont wire
