سنسور رطوبت خاک YL69 همراه ماژول رله 12 ولت مناسب آبیاری اتوماتیک گلدان هوشمند
This is a simple water sensor can be used to detect the moisture of the soil, when the soil water deficit, the relay is switched off, and vice versa relay. It can be used to produce an automatic watering device.
Adjust the soil humidity control threshold through the potentiometer, which can automatically water the vegetable garden, garden, soil moisture in household flower pots, various electronic games, etc., with high-power relays, which can control high-current equipment, less than The fixed-humidity automatic start relay pull-in is greater than the set-humidity automatic disconnection and has a time-delay function.
It solves the problem of non-delayed humidity critical state relays flickering continuously. It is a simple and practical soil humidity control system.
