The XH-M131 is a useful module for controlling load or light based on the brightness of the surroundings. An example of using it is controlling a street light at night. When the load is connected to the NO terminal, at night, the relay module of this unit kicks in to activate the load or light (indicated by a blue LED). During the day, the relay module turns off to turn off the load or light. The light sensor is an LDR connected via two wires. Light detection sensitivity can be adjusted via an onboard potentiometer. The opposite function can be achieved by connecting the load to the NC terminal.
