Perfect for fire safety projects
This sensor works flawlessly with my Arduino Uno. The sensitivity is adjustable via the potentiometer, which makes it easy to calibrate for different environments. Great build quality.

Reliable and responsive
We bought ten of these for our workshop kits. They are consistent in performance and the digital output makes integration very simple. Highly recommended for educational purposes.

Exactly as described
Fast shipping and the module arrived in perfect condition. Tested it immediately and it reacts very quickly to open flames. The analog output allows for distance estimation too.

Good value, easy to use
Used this for a university project on home automation. It detected the flame from a lighter instantly. The only downside is that the documentation could be slightly more detailed for beginners.

Solid sensor module
Works well for detecting candle flames and lighters. Be aware that strong sunlight can sometimes trigger false positives if not shielded properly, but that is expected for this technology.

Great addition to my robot
Integrated this into my fire-fighting robot. The response time is impressive, and the compact size fits perfectly on the chassis. Very happy with this purchase.
Q: How do I adjust the sensitivity of the detection?
A: There is a blue potentiometer on the board. Use a small screwdriver to turn it clockwise to increase sensitivity or counter-clockwise to decrease it while testing with a flame source.
Q: Does this module work with 3.3V logic boards like the ESP32?
A: Yes, the module operates within a 3.3V to 5V range, making it fully compatible with 3.3V logic boards such as the ESP32 and Raspberry Pi.
Q: Is a library required to use this with Arduino?
A: No external library is strictly required. You can read the digital output using standard digitalRead() functions or the analog output using analogRead(). Sample code is available on our wiki.
Q: Can this sensor detect smoke or only open flames?
A: This sensor is designed specifically to detect the wavelength of open flames (760nm-1100nm). It is not a smoke detector and will not reliably detect smoke particles alone.
Q: What is the maximum effective detection distance?
A: Under normal indoor lighting conditions, the effective detection range is typically between 0cm to 100cm, depending on the size and intensity of the flame.
