Humidity Sensitive Switch Relay Humidity Controller Humidity Sensor Module, 501 Original

Features:With HR202 humidity sensor.The comparator output directly drive relays, connect to AC 220V power or other equipment.Adjust the temperature detection threshold with potentiometer.Enable you to connect wired humidity sensor with pins on sensor port.With 4 3mm screw holes.Function: Humidity detection, humidity sensor, environmental humidity detection, with relay output, directly control the power supply of related equipment.Specification:Power: DC 5V, >150mAMax Load: AC 250V 10A or DC 30V 10ABoard Size: approx. 50 X 26 X 19 mm/1.97 X 1.02 X 0.75 inNote:1. Humidity sensor is most sensitive to environmental humidity, generally used to detect the humidity of the surrounding environment.2. When the environmental humidity exceeds the set threshold, the relay is pulled in and the common end is connected with the usual start. When the ambient humidity is lower than the set threshold, the relay is disconnected and the common terminal is connected to the normally closed terminal.3. Common end, normally open, normally closed, the 3 ports are equivalent to a double control switch, when the relay coil is power, the common end and common start, without electricity, the common end and the normally closed end.1 X Module Board
