Great for learning embedded systems
Bought this for a university project on IoT safety systems. The digital output makes interfacing with Arduino incredibly simple. Documentation could be better, but standard tutorials work fine.

Exceeded expectations
For the cost, you really can't beat this. It's sensitive enough to detect a match strike from a reasonable distance. Shipping was fast and the component arrived well-packaged.

Perfect for my robotics project
This sensor works exactly as described. I integrated it into a small fire-fighting robot, and the detection range is impressive for such a compact module. The potentiometer makes it easy to tune sensitivity.

Good value, needs calibration
Solid build quality for the price. It took a few minutes to calibrate the threshold using the onboard pot, but once set, it reliably detects candle flames from about 60cm away.

Reliable and fast response
We used ten of these in our competition bots. They all performed consistently with fast reaction times when exposed to a lighter flame. Highly recommended for educational kits.

Compact and effective
Very small form factor which helped in my tight chassis design. Just be aware that strong sunlight can sometimes trigger false positives if sensitivity is maxed out.
Q: Does it work outdoors in direct sunlight?
A: Direct sunlight contains IR radiation that can interfere with detection. We recommend shielding the sensor or adjusting the sensitivity potentiometer carefully if used in bright outdoor environments.
Q: What is the maximum voltage this board can handle?
A: The module operates safely between 3.3V and 5V DC. Applying voltage higher than 5V may damage the comparator chip and the IR receiver.
Q: Does this module output analog or digital signals?
A: This specific model provides a digital switch output (HIGH/LOW). If you need analog values representing flame intensity, please look for our analog variant.
Q: Can this sensor detect smoke?
A: No, this is a flame sensor designed to detect the specific wavelength of fire light (760nm-1100nm). It cannot detect smoke particles; you would need a dedicated smoke sensor for that.
Q: Is the mounting hole size standard for M3 screws?
A: Yes, the mounting holes are 3.0mm in diameter, which is compatible with standard M3 screws and standoffs commonly used in electronics projects.
