Flame Sensor 5mm

Key Features

1. Sensor Type: Often uses an infrared (IR) photodiode or phototransistor tuned to detect the specific IR wavelength emitted by flames.
2. Compact Size: The 5mm refers to the diameter of the IR sensor component, making it suitable for space-constrained applications.
3. Detection Angle: Typically 60° - 120°, depending on the module design.
4. Sensitivity: Adjustable through a built-in potentiometer on the module.
5. Power Supply: Usually operates at 3.3V to 5V, compatible with microcontrollers like Arduino, Raspberry Pi, and similar platforms.
6. Output Pins:
   • Digital Output (DO): Provides a HIGH or LOW signal based on the flame detection threshold.
   • Analog Output (AO): Outputs an analog voltage corresponding to the intensity of the detected flame.

Applications

1. Fire Detection Systems: Alerts or activates suppression systems in case of fire.
2. Robotics: Fire-fighting robots to detect and extinguish flames.
3. Industrial Equipment: Monitors gas burners or welding equipment.
4. DIY Projects: Used in home automation or educational setups for flame detection.
