How do I wire the flame sensor module?
Connect VCC to 3.3 V or 5 V and GND to ground, then read the output pin. Check the labels on the module board for the output pins, and use the onboard potentiometer to adjust sensitivity.
Can it be triggered by ordinary light?
Yes. The sensor responds to infrared light, so sunlight and some lamps can cause false triggers. Reduce the sensitivity with the potentiometer and shield the sensor from direct light sources where needed.
