Full description

The XH-M131 is a self-contained light-controlled switch. Its photoresistor continuously monitors ambient brightness, and when the level crosses the threshold you set with the onboard potentiometer, the 5V relay switches your connected load - no programming or microcontroller required.

Use it to automatically turn on garden or balcony lights at dusk, switch display lighting, control chicken-coop doors or build daylight-dependent automation. The relay contacts can switch small mains or low-voltage loads (check the relay rating printed on the module before connecting).

Power: DC 5V supply. Adjustable sensitivity, LED status indicator, screw terminals for easy wiring.
