A ready-built light-controlled switch: a photoresistor on a short lead senses ambient brightness and the on-board relay flips a load when it crosses the threshold you set with the blue trimmer. The relay is a Songle SRD-12VDC-SL-C, so the board runs from 12V, and its NO / COM / NC contacts are printed 10 A at 250 V AC. Good for dusk-to-dawn lighting or any brightness-triggered automation.
Key features
- Switches a load on ambient light level, no code needed
- CdS photoresistor on a plug-in lead, so it can sit away from the board
- Songle SRD-12VDC-SL-C relay, SPDT
- Contacts printed 10 A at 250 V AC / 10 A at 30 V DC
- Threshold set with the on-board ADJ trimmer
- Screw terminals for 12V in and for the switched load
