ITEM NAME:Humidity Sensor Switch Relay Module Hygrometer Control Board DIY Practice Description: - Adopt high-quality HR202 humidity sensor - The comparator outputs directly the driver relays,connecting with 220V AC or other equipment - Designed with a potentiometer to adjust the detection threshold for temperature - Pinheader can be installed with the sensor interface,which can connect with the humidity sensor with the lead wire - Widely used for Humidity detection, humidity sensor, environmental humidity detection, with relay output, directly control the power supply of related equipment Specification: - Power: DC 5V >150mA - Max Load: AC 250V 10A / DC 30V 10A - Board Size: approx. 50mm X 26mm / 1.97 X 1 Inch - Color: as shown in the display pictures Size Chart: 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. Package Included: 1 Piece Humidity Sensor Relay Module.Pinheader can be installed with the sensor interface,which can connect with the humidity sensor with the lead wire. 1 Piece Humidity Sensor Relay Module. - Adopt high-quality HR202 humidity sensor. - Max Load: AC 250V 10A / DC 30V 10A.
