Through the potentiometer adjusting soil moisture threshold control, automatic in garden, garden automatic watering, family flowerpot soil humidity control, all kinds of electronic games, with high power relay, can control large current device, less than setting humidity automatic start relay, greater than setting humidity automatically disconnect and delay function, without delay of critical humidity state relay don’t stop flicker problem solving
When the soil moisture is lower than the set humidity, the relay will automatically draw in, start the spray, water pumps, and so on to do humidifying movement, and when the humidity exceeds the appropriate level, it will automatically stop.
