Jordfuktsmätare sensor (Soil moisture Sensor)

The threshold of soil moisture control can be adjusted by potentiometer, which can automatically control vegetable garden, garden watering, soil moisture of family flowerpot, various electronic competitions, electronic building blocks, Arduino design, etc.

Product introduction:

1. Using the high-quality soil sensor produced by our company to detect soil moisture, the surface is treated with nickel plating, which has widened sensing area, can improve the conductivity, prevent the problem of easy rusting in contact with soil, and prolong the service life;

2. The product can control soil moisture in a wide range, and control the corresponding threshold through potentiometer regulation. When the humidity is lower than the set value, DO output high level, and when the humidity is higher than the set value, DO output low level.

3. Comparator uses LM393 chip and works stably.

4. Working voltage 3.3V-5V

5. Fixed bolt hole 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 board digital output interface (0 and 1)

Module usage instructions:

1. Sensors are suitable for soil moisture detection.

2. The blue potentiometer in the module is used to adjust the threshold value of soil moisture. The larger the humidity is controlled clockwise, the smaller the counterclockwise.

3. Digital output D0 can be directly connected with single-chip computer, which can detect high and low levels, thereby detecting soil moisture.
