Soil Humidity Hygrometer Detection Module Moisture Water Sensor

NZ$17.44 NZ$9.27







(1) The surface is treated with nickel plating, which can improve the conductivity, prevent the problem of easy rusting in contact with the soil, and prolong the service life
(2) The humidity of the soil can be controlled in a wide range, and the corresponding threshold is controlled by the potentiometer. When the humidity is lower than the set value, the DO output is high, and when it is higher than the set value, the DO output is low
(3) The comparator uses LM393 chip and works stably
(4) Working voltage 3.3V-5V
(5) Fixed bolt holes for easy installation

Wiring instructions (3-wire system)
1 VCC external 3.3V-5V
2 GND external GND
3 DO small board digital output interface (0 and 1)

Instructions for use:
1. The sensor is suitable for moisture detection of soil;
2. The blue potentiometer in the module is used for the threshold adjustment of soil moisture. When it is adjusted clockwise, the humidity will be controlled, and the counterclockwise will be smaller.
3. The digital output D0 can be directly connected to the single-chip microcomputer, and the high and low levels are detected by the single-chip microcomputer, thereby detecting the soil moisture.

Package includes:
1* module;
1* soil sensor;
2*DuPont line
