5V 1 Channel Humidity Sensor Relay Module is an electronic switch that turns a device on and off depending on the humidity of the surrounding atmosphere.
This self-contained switching module energises / de-energizes a relay based on the humidity level. Â Â Just add 5V power and hook up the load you want to control, then adjust the potentiometer to set the relative humidity level at which you want the relay to switch between ON / OF
it can use this type of module for applications such as automatically turning on an exhaust fan when the humidity gets above a preset level, as might be the case in a greenhouse or aquarium room, or you could use it to energise a misting system, such as for orchids when the humidity drops below a preset level
