Operating Voltage 3.3~5VDC 15.86 ZAR inc for 1 Each 84 in Stock Add Specifications, Prices & Availability may change without notice. Images are for illustration purposes only. E&OE Features Instructions for use: The sensor is suitable for soil moisture detection. The blue potentiometer on the module is used for soil moisture limit adjustment, clockwise. The blue potentiometer on the module is for soil moisture limit adjustment, clockwise adjustment, the higher the controlled humidity, the lower the counterclockwise adjustment. Digital output D0 can be directly connected to the microcontroller, through the microcontroller to detect the 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 moisture. Product description: The product can control the soil moisture in a wide range, through the potentiometer to adjust the corresponding valve value control, 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. The comparator adopts LM393 chip, which works stably. Operating voltage 3.3V-5V There is a fixed screw hole, easy to install Size: 3.2 cm * 1.4 m Note: Please allow 1-2cm measuring deviation due to manual measurement.
