Exactly what I needed
Used for a model railway lighting system. Stable performance over several weeks without any issues.

Good but needs tuning
The relay functions well but took some time to adjust the potentiometer for my specific lighting conditions.

Great for automation
Works perfectly with my 12V LED strip setup. Very sensitive to light changes and the relay clicks securely.

Decent module
Works as intended but the LDR range is limited. Good for close proximity detection rather than large areas.
Q: Does this come with connecting wires?
A: No, wires are not included. You will need to solder or use screw terminals for connections.
Q: Can I power this with 9V battery?
A: It is designed for 12V DC. Using 9V may not provide enough voltage to trigger the relay reliably.
Q: How do I reverse the light logic?
A: Use the jumper cap or switch on the board to toggle between Light and Dark trigger modes.
Q: Is the relay Normally Open or Normally Closed?
A: The module provides Common, Normally Open, and Normally Closed terminals for flexible wiring.
Q: Can it handle 220V household lights?
A: Yes, the relay is rated for 250VAC, but please ensure proper insulation and safety measures.
