Instructions:
1."+" connects positive; "-" goes to negative. Don' connect reversely or the chip will be burnt out. There is a LED indicator at the P mark on the board. It will if the module operates normally.
2.Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. For example, DO outputs low level when the moisture reaches 50% now, then I clockwise rotate the potentiometer to increase the detection threshold. At this time, DO outputs a low level only when the moisture reaches a point higher than 50%.
3. If you clockwise rotate the potentiometer to an extent that the LED indicator which marked "S" is light, that means the testing threshold has been surpassed. Counterclockwise rotating to surpasses the threshold too. The module will not work well if the detection threshold is invalid. NOTE: The threshold adjustment only works for using the DO output.
