Perfect for Arduino Projects
Works exactly as described. Connected it to my Uno and detected a lighter flame instantly. Potentiometer helps adjust sensitivity.

Needs calibration
Works but took some time to tune the potentiometer correctly. Sunlight triggers it sometimes indoors.
Q: Does it output analog values?
A: This module provides a digital output. For analog reading, you would need a different sensor type.
Q: Can I use this outdoors?
A: It is designed for indoor use. Direct sunlight may interfere with detection accuracy.
Q: What is the maximum range?
A: Detection range varies by flame size, typically up to 100cm for a strong flame source.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works with 3.3V logic systems like Raspberry Pi. Ensure proper GPIO configuration.
Q: Is a library available?
A: It functions as a simple digital input, so no specific library is needed. Standard digitalRead works.
