12V Soil hygrometer Humidity Detection Module Moisture Monitoring Module Automatic Watering Device Garden Sensor

Descriptions:
When soil moisture is below the set humidity, the relay will automatically pull start the spray, pump, do humidifying action. It will stop automatically when it reaches the set humidity.

Applications:
By adjusting the soil moisture threshold value on the potentiometer, you can automatically water your vegetable farm and garden, and control soil moisture in your flowerpots. The large power relay enables you to control large current equipment. When the humidity is below the set value, the relay starts; when the humidity is higher than the set value, the relay shuts down. The delay function can solve the problem that when in no delay moisture critical state, the relay keeps flickering. It is easy and practical to use.

Electrical parameters:
Supply voltage: 12V DC
Input current: more than 100mA
Load: AC 250V 10A or DC 30V 10A
