Documentation could be clearer
The hardware is fine, but I struggled to find example code for ESP32 initially. Works great once configured.

Great Quality Module
Solid PCB and connector. The analog output makes it easy to read varying intensities. Fast delivery too.

Reliable Detection
I used this for a kitchen safety prototype. It detects candle flame from a good distance. Highly recommend.

Good sensor, needs tuning
The sensor works well but you need to adjust the threshold in code to avoid false positives from bright light.
Q: Does this work with 3.3V logic?
A: Yes, it operates between 3.3V and 5V.
Q: Do you provide a library for this?
A: Yes, example code is available on our Wiki page for Arduino IDE.
Q: Can this be used outdoors?
A: It is not waterproof. Outdoor use requires an enclosure to protect from moisture.
Q: Is the output digital or analog?
A: This module provides an analog voltage output proportional to flame intensity.
Q: What is the detection range?
A: Typically detects a candle flame within 100cm depending on ambient light.
