Smart Electronics Soil Moisture Hygrometer LM393 Soil Moisture Sensor Development Board 5V for Robot Smart Car Specification: Origin: Mainland China Instructions for Use: 1. The sensor is suitable for moisture detection of soil. 2. The blue potentiometer in the module is used for soil humidity threshold adjustment, clockwise.The blue potentiometer in the module is for soil humidity threshold adjustment, clockwise adjustment, the greater the controlled humidity will be, counterclockwise the smaller. 3. Digital output D0 can be directly connected to the microcontroller, through the microcontroller to detect Digital output D0 can be directly connected to the microcontroller, through the microcontroller to detect the high and low levels, and thus to detect the soil humidity. Product Description: 1. The soil sensor produced by our company is used for soil humidity detection. Nickel-plated treatment, there is a wider sensing area, can be conductive, easy to rust in contact with the soil,The problem of contact with the soil is easy to rust, prolonging the service life. 2. The product can control the humidity of the soil in a wide range, through the potentiometer to adjust the control of the corresponding Valve value, humidity below the set value, DO output high level, higher than the set value, DO output low level. When the humidity is lower than the set value, DO outputs high level; when higher than the set value, DO outputs low level. 3. The comparator adopts LM393 chip, which works stably. 4. Operating voltage 3.3V-5V 5. There is a fixed bolt hole, easy to install 6. Size: 30*15*5mm/1.17*0.59*0.2in
