Fast response time
The reaction time is impressive. As soon as the IR spectrum of a flame hits the sensor, the LED indicator lights up and the output goes low. Highly recommended for automation projects.

Reliable detection range
I integrated this into a home safety prototype. It consistently detects a candle flame up to 80cm away in a dark room. Very happy with the stability of the digital output.

Solid component for prototypes
We bought ten of these for our workshop. Nine worked flawlessly immediately. One had a loose pin which we soldered back on. Overall, excellent quality for prototyping purposes.

Easy to interface
As a beginner, I found this very easy to connect to my microcontroller. Just three pins needed: VCC, GND, and DO. The documentation online is also quite helpful for getting started.

Good value, needs calibration
Great little module for the price. Out of the box, it was a bit too sensitive to ambient light, but after turning the potentiometer slightly, it works perfectly for detecting flame sources only.

Perfect for my Arduino fire alarm project
This sensor works exactly as described. I tested it with a lighter from about 30cm away and it triggered instantly. The sensitivity pot makes it easy to calibrate for different environments.
Q: Can I power this directly from a 9V battery?
A: No, the operating voltage is strictly 3.3V to 5V DC. Connecting it directly to a 9V battery will damage the module. Please use a voltage regulator or a compatible microcontroller board to supply the correct voltage.
Q: Can this sensor detect sunlight or just artificial flames?
A: The sensor detects infrared waves in the 760nm-1100nm range. While strong sunlight contains IR, the module is primarily tuned for the specific spectrum of a flame. You can adjust the sensitivity potentiometer to ignore ambient light sources like sunlight or lamps.
Q: What is the maximum distance this module can detect a standard lighter flame?
A: Under normal indoor lighting conditions, the effective detection range for a standard lighter flame is typically between 30cm and 80cm. This varies based on the sensitivity setting and ambient light levels.
Q: Does this module provide an analog output or only digital?
A: This specific model provides a digital switching output (0 and 1) via the DO pin. If you require analog readings to measure flame intensity, please look for our AO variant models.
Q: Is a library required to use this with Arduino?
A: No external library is required. Since the output is digital, you simply read the pin state using the standard digitalRead() function in your Arduino sketch. It acts like a simple switch.
