Sensitive but needs tuning
Good detection range for a small module. You do need to spend some time calibrating the sensitivity screw to avoid false positives from bright lights. Overall satisfied.

Fast delivery
Arrived quickly and was packaged well in anti-static foam. The pins were straight and ready to solder. No issues during initial testing.

Documentation lacking
The hardware works fine, but the included paper had very little info. I had to search online for wiring diagrams. Would be nice to have a QR code to a guide.

Perfect for safety prototype
Integrated easily into my home automation test bench. The digital output is clean and the response time is quick when exposed to a lighter flame at close range.

Great for Arduino projects
Works exactly as described. I used this for a hobby safety alarm prototype and the sensitivity is adjustable via the potentiometer. Very easy to interface with microcontrollers.
Q: What is the difference between the 3-wire and 4-wire versions?
A: The 4-wire version includes an analog output pin (AO) for variable signal reading, while the 3-wire version typically provides only digital output (DO).
Q: What is the maximum detection distance?
A: Detection range depends on flame intensity, but typically works reliably within 100cm for a standard lighter flame under normal conditions.
Q: Is this compatible with 3.3V logic boards like ESP32?
A: Yes, the module operates within the 3.3V to 5V DC range, making it compatible with ESP32, Arduino, and Raspberry Pi GPIO pins.
Q: Does sunlight trigger false alarms?
A: Direct sunlight or strong IR sources can interfere with detection. We recommend testing sensitivity indoors or shielding the sensor from direct sun.
Q: Can I connect this directly to a Raspberry Pi?
A: Yes, connect VCC to 5V or 3.3V, GND to GND, and DO to a GPIO pin. Ensure you configure the GPIO as an input in your software.
