Flame Sensor Module – Fire Detection Sensor for Arduino and Robotics
The Flame Sensor Module detects infrared light emitted from flames and is perfect for building fire detection, safety alarm systems, and robotic fire-fighting projects. It is designed for easy integration with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms.
 
Key Features:
Flame Detection at 760–1100 nm
Infrared sensor tuned to the wavelength range of flame radiation, ensuring reliable fire detection.
Dual Output: Analog and Digital
Provides an analog signal for varying flame intensity and a digital HIGH/LOW signal for threshold-based alerts.
Adjustable Sensitivity
Onboard potentiometer lets you set the detection threshold to match your environment.
Built-in Status Indicators
Power and signal LEDs give visual feedback on detection status.
Wide Compatibility
Works with most 3.3V and 5V microcontrollers like Arduino, STM32, and ESP boards.
 
Applications:
Fire detection systems
Robotic firefighting projects
Automatic flame alarms
Gas leakage + flame monitoring
Educational safety simulations
