Sensitive detection
Picks up lighter flames easily. Just make sure to calibrate it for your environment to avoid false positives.

Needs some tuning
Took me a while to get the threshold right. Works now but documentation was sparse for beginners.

Great for Arduino projects
Works perfectly with my Uno. Sensitivity is adjustable via the potentiometer. Very responsive to lighter flames.
