1.  This is a simple moisture sensor that can be used to detect soil moisture. When the soil is short of water, the module outputs a high level and vice versa.Use this sensor to create an automatic flower watering device that lets your garden plants be managed by no one.
2. Adjustable sensitivity (blue digital potentiometer in the figure)
3. Working voltage 3.3v-5v
4. module dual output mode, digital output simple, analog output more accurate.
5. Fixed bolt hole is provided for easy installation
6. small PCB size: 3cm * 1.6cm
7. Power indicator (red) and digital switch quantity output indicator (green)
8. The comparator USES LM393 chip and works stably

Working Instruction

1. The soil moisture module is the most sensitive to environmental humidity and is generally used to detect soil moisture.
2. When the soil humidity of the module fails to reach the set threshold, the DO port outputs a high level. When the soil humidity exceeds the set threshold, the module D0 outputs a low level.
3. The digital output D0 of the small plate can be directly connected with the microcontroller, through which the high and low level can be detected to detect soil moisture.
4. small plate digital output DO can directly drive the store relay module, buzzer module, etc., which can constitute a soil moisture alarm equipment;
5. AO output of small plate simulation quantity can be connected with AD module, and through AD conversion, a more accurate value of soil moisture can be obtained;
