IR Flame Sensor Module - 760nm to 1100nm Fire Detection | Compoden
IR Flame Sensor Module - Detects 760nm to 1100nm Wavelengths
The IR Flame Sensor Module detects fire or other infrared light sources within the 760nm to 1100nm wavelength range. It provides a digital output when a flame is present, making it ideal for fire alarm systems, robotics, and safety automation. The on-board potentiometer allows sensitivity adjustment for various detection distances.

What You Can Build With This
- Fire alarm system with buzzer alert
- Flame-following robot
- Automatic fire extinguisher trigger
- IoT fire notification system using ESP8266
Compatibility
Compatible with 3.3V and 5V microcontrollers including Arduino Uno, Nano, Mega, Raspberry Pi, and ESP32. Connect the digital output directly to any I/O pin; no level shifting is required for 5V-tolerant boards. Operates reliably with standard logic levels.
Wiring Notes
Wire VCC to 3.3V or 5V, GND to ground, and OUT to a digital input pin. Adjust the potentiometer until the green LED lights at your desired detection distance. Avoid placing the sensor in direct sunlight to prevent false triggers.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, connect VCC to 5V, GND to GND, and OUT to any digital pin (e.g., D2). Use digitalRead() to detect flame.
Can it detect fire through glass or plastic?
The sensor detects specific infrared wavelengths which may be attenuated by glass or plastic; direct line-of-sight to the flame works best.
How do I adjust sensitivity?
Use a small screwdriver to turn the on-board potentiometer clockwise to increase sensitivity or counterclockwise to decrease it.
