FC-28-E Soil Humidity Detection Sensor Module
Nickel plating, widen sensor area, high electric conduction performance, anti-rust. Wide range detection, relay closing when the soil humidity higher than setting value, and break when lower than setting value. With delay function, delay time: 3~5s, when humidity value reach critical point, relay shows flash strobe. Use high quality songle relay, Max. load up to 1500W. With power indicator and indication of relay close.
Specification: Working voltage: DC 5V, input current: >=100mA, load: 250V / 10A or 30V / 10A, Max. load: 1500W
