Supply voltage: 12VDC Input Current: more than 100ma
Load: 250V 10A AC or 30V 10A DC ( below current in this range can be used)
The surface is nickel-plated and has a wide sensing area, which can improve the conductivity and prevent the problem of rust in contact with the soil.
The corresponding threshold is controlled by the potentiometer. When the humidity is lower than the set value, the relay is activated. When the value is higher than the set value, the relay is disconnected.
With delay function, delay 3-5 seconds, when the humidity is detected in the critical state, the relay will not flash, stroboscopic phenomenon.
Suitable for moisture detection of soil.
Automatically watering vegetable gardens, gardens, and control of soil moisture in family pots.
