Exceeded expectations
I bought a pack of five for a classroom project. All units worked flawlessly out of the box. The potentiometer allows for precise calibration which is essential for our varying test environments.

Easy to use for beginners
As someone new to electronics, I found this module very straightforward to connect. The three pins are clearly labeled, and the onboard LED indicator helps visualize when a flame is detected.

Reliable and fast response
Fast response time when exposed to a heat source. I integrated two of these into my home security prototype and they have been stable for weeks. Highly recommended for DIY enthusiasts.

Good detection range
I tested this with a lighter and it detected the flame from about 80cm away. The digital output makes it easy to interface with microcontrollers. Only giving 4 stars because the documentation could be more detailed.

Perfect for my Arduino fire alarm project
This sensor works exactly as described. The sensitivity adjustment is very responsive, allowing me to tune it specifically for candle flames without false alarms from ambient light. Great value for the price.

Solid component for the price
Works well for general fire detection tasks. The build quality is decent for a budget module. Just ensure you provide a stable 5V supply for consistent readings.
Q: Does this come with mounting screws?
A: No, the package typically includes only the PCB modules. Mounting screws are not included, but the board features standard 3mm mounting holes compatible with common M3 standoffs and screws.
Q: Can this sensor detect sunlight or only artificial flames?
A: The sensor is tuned to the wavelength of a flame (760nm-1100nm). While strong direct sunlight contains these wavelengths and may trigger it, the adjustable sensitivity potentiometer allows you to calibrate it to ignore normal ambient light levels.
Q: Is this module compatible with Raspberry Pi?
A: Yes, it is compatible. Since the module operates at 3.3V to 5V, you can connect the VCC to the 3.3V or 5V pin on your Raspberry Pi and the DO (Digital Output) to a GPIO pin. Ensure you handle the voltage levels correctly.
Q: What is the maximum distance for reliable detection?
A: Under normal indoor lighting conditions, the sensor can reliably detect a standard candle flame at a distance of approximately 80cm to 100cm. This varies based on the intensity of the fire source and ambient light.
Q: Can I use this to detect gas leaks?
A: No, this is strictly an optical flame sensor designed to detect the light spectrum emitted by a fire. It cannot detect gas leaks. For gas detection, you would need a specific combustible gas sensor module.
