Works but range varies
Functionality is okay, but the detection range seems shorter than expected in bright rooms.

Good sensitivity
Detects flame quickly. Had to adjust the potentiometer slightly to avoid false alarms from sunlight.

Great value
Cheap and effective. The relay output makes it easy to connect to higher voltage alarms.
Q: What is the maximum current the relay can handle?
A: The onboard relay supports up to 10A at 250VAC or 30VDC.
Q: Is it sensitive to infrared heaters?
A: It detects IR radiation in the flame spectrum. Strong IR sources may trigger it, so calibration is recommended.
Q: Can this operate on 5V instead of 12V?
A: This specific model is designed for 12V input. Using 5V may result in unstable relay operation.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the board. Turn it clockwise to increase sensitivity.
Q: Does it work with Arduino?
A: Yes, you can connect the DO pin to any digital input pin on your Arduino board.
