Product Description:
Soil Moisture Humidity Sensor Hygrometer Module for Arduino 2560 UNO 1280 FZ0268

Description:
Color Black + Yellow
Material Plastic + iron
Features Soil Humidity Sensor
Specification Sensitivity adjustable, Uses LM393 chip, Power supply: 3.3V or 5V
Application DIY experimental development

Small plate interface description (4-wire)
1 VCC external 3.3V-5V
2 GND external GND
3 DO small board digital output interface (0 and 1)
4 AO the small plates analog output interface
Instructions for use:
Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
2 module in the soil humidity less than a set threshold value when the DO port output high, when the when soil humidity exceeds the threshold value is set, the module D0 output low;
3 small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and thus to detect soil moisture;
4 small plates digital output DO shop relay module can directly drive the buzzer module, and which can form a soil moisture alarm equipment;
5 small plates analog output AO and AD module connected through the AD converter, you can get more accurate values of soil moisture.
