HiLetgo 2pcs HR202 Humidity Sensor Relay Switch Humidity Control Switch DC 5V 1 Channel Humidity Sensor Relay Module for Arduino
HiLetgo 2pcs HR202 Humidity Sensor Relay Switch Humidity Control Switch DC 5V 1 Channel Humidity Sensor Relay Module for Arduino
Application: For ambient humidity detection,high quality humidity sensor with relay output to direct control of related equipment powerParameters:Supply Voltage: 5VDC; Maximum Load: 250V/10A AC or 30V/10A DC,or less than this powerModule Instructions:Humidity sensor is most sensitive to environmental humidity,generally used to detect the ambient humidity;2)The relays pull in,so the common end and normally open end connect when the ambient humidity exceeds the set threshold;The relays break off,so the common end and normally closed end connect when the ambient humidity is below the set threshold 3)Common end,normally open end & normally closed end is equivalent to a dualcontrol switch.The common end and the normally open connect when the relay live electricity ;the common end and normally closed end connect when the relay is out of electricity.Package Included:2Humidity Sensor Switch Relay Module
