Flame Sensor Module | IR 1-Channel |

Flame Sensor Module | IR 1-Channel | 4 Pin

The Flame Sensor Module is designed to detect fire or flame sources by sensing infrared light in the 760–1100 nm wavelength range. It provides both analog and digital outputs, making it versatile and easy to integrate into safety and automation projects.

It’s widely used in fire detection systems, alarm systems, and safety robots, and is fully compatible with Arduino, ESP8266/ESP32, and other microcontrollers.

Highlights

• Detection Range: Up to ~80 cm (depending on flame size and intensity)

• Wavelength Range: 760 – 1100 nm (IR light from flames)

• Operating Voltage: 3.3 V – 5 V

• Interface: 4-pin (VCC, GND, AO, DO)

• Outputs:

  • Analog output (proportional to flame intensity)

  • Digital output (threshold adjustable via onboard potentiometer)

• Compact design with mounting holes for projects

💡 Ideal for: Fire detection, safety systems, flame alarm projects, and robotics with flame detection capability.
