Good value
Documentation could be clearer about wiring diagrams, but overall it functions well. Detection range is decent for indoor use.

Sensitive detection
Picks up flame quickly but needs tuning depending on ambient light. Good value for hobbyists building smart vehicle prototypes.

Great for Arduino projects
Works perfectly with my Uno board. The sensitivity is adjustable via the potentiometer. Used it for a safety prototype and it responded instantly to a lighter flame.
Q: Does this work with Raspberry Pi GPIO?
A: Yes, it is compatible with Raspberry Pi as long as you connect it to the 3.3V or 5V pin accordingly.
Q: Is sample code included in the documentation?
A: Yes, the included documentation provides basic sample code for Arduino to help you get started quickly.
Q: Can it detect sunlight or will it false trigger?
A: It may trigger under strong direct sunlight. We recommend testing sensitivity in the intended environment.
Q: What is the detection angle of the sensor?
A: The detection angle is approximately 60 degrees. Please aim the sensor directly at the potential flame source.
Q: Is this module waterproof for outdoor car use?
A: No, this is an indoor electronic component. It should be housed in a protective enclosure if used outdoors.
