Flame Sensor Overview
A flame sensor is a device designed to detect and respond to the presence of a flame or fire. It is commonly used in fire detection systems, safety applications, and industrial settings. The sensor typically operates by detecting infrared (IR) light emitted by flames.
IR Flame Sensors:
Detects infrared radiation from flames.
Suitable for detecting flames from materials that burn with an IR spectrum (e.g., wood, paper, gasoline).
Working Principle of IR Flame Sensors:
An IR flame sensor consists of an IR receiver, often a photodiode, that detects infrared light. When a flame is present, it emits a specific wavelength of IR light that the sensor detects. The sensor typically outputs a digital signal indicating the presence (LOW) or absence (HIGH) of a flame.
Components of a Typical Flame Sensor Module:
IR Receiver (Photodiode): Senses the IR light emitted by a flame.
Comparator Circuit: Compares the received IR light against a threshold to output a digital signal.
Sensitivity Adjustment Potentiometer: Allows for tuning the sensitivity of the sensor.
Output Pins:
VCC: Power supply, typically 5V.
GND: Ground connection.
OUT: Digital output pin.
Applications:
Fire Detection Systems: Used in residential, commercial, and industrial fire alarm systems.
Safety Equipment: Integrated into equipment to shut off fuel supply in case of a fire.
Robotics: Enables robots to detect and respond to fire.
Gas Burners and Boilers: Ensures safe operation by detecting and responding to flames.
