Through potentiometer regulation soil humidity control valve value, can automatically on Garden, Garden automatically watering, family pot soil humidity of control, various electronic competition, , with high power following electric, can control big current device, is less than set humidity automatically started following electric sucking-in, is greater than set humidity automatically disconnect, and has delay function, solve no delay of humidity critical state following electric kept of flashing of problem, is a simple practical of soil humidity control system.
Supply voltage: 12VDC input current: more than 100mA
Load 250V AC or DC 30V 10A (current below this range can be used)
1. humidity detection sensor applied to soil;
2. the blue potentiometer modules are for soil moisture threshold adjustment, adjust clockwise, humidity will be under the control of the greater and turning it counterclockwise smaller;
3. because of this module with the time delay function, adjust the humidity value, about every mobility need to wait 5-8 seconds, relay changes in corresponding changes in the Green LED lights, until transferred to meet the requirements.
4. product connection information please refer to the following picture.
NO Wiring Diagrams , when the sensor was triggered, the device will work.
1 x soil humidity sensor
1 x Relay Control Module
