1. This high-quality soil relay board module can detect soil moisture without worrying.
2. The nickel-plated surface expands the sensing area, which improves conductivity, prevents rust problems with soil and prolongs service life.
3. When this module puts into use, the corresponding threshold is controlled by adjusting the potentiometer, the humidity is lower than the set value, and the relay is activated, and when the humidity is higher than the set value, the relay is disconnected.
4. With delay function, this relay board module can delay 5‑8 seconds when use it.
5. When humidity is detected in a critical state, the relay module will not change, and flicker will occur.

Module Description:
1. The humidity detection sensor applied to the soil;
2. The blue potentiometer module is used to adjust the soil moisture threshold. It is adjusted clockwise, and the humidity will decrease counterclockwise under greater control.
3. Because this module has a delay function to adjust the humidity value, it takes about 5-8 seconds to wait for each movement, and the green LED light corresponding to the change of the relay will also change until the movement meets the requirements.
