Instructions:

1.\"+\" connects power; \"-\" goes to negative. ' connect reversely or the chip will be burned out. There is an LED power indicator at P on the board. It will if the module works normally.

2.Turn the blue potentiometer clockwise/counterclockwise to increase/decrease the detection. For example, DO outputs low level when the humidity reaches 50% now, then I turn the potentiometer clockwise to increase the detection. At this time, DO outputs a low level only when the humidity reaches a higher than 50%.

3. If you turn the potentiometer clockwise to a degree that the LED indicator marked \"S\" lights up, it means that the testing has been exceeded. Counterclockwise rotating to exceed as well. The module will not work if the detection is invalid. NOTE: The adjustment only works for the use of the DO output.
