Function: Detects the presence of flame or fire by sensing infrared light emitted from a flame source.

Sensor Type: Infrared (IR) flame sensor with photodiode or phototransistor detector.

Operating Voltage: 3.3V to 5V DC – compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers.

Detection Range: Typically detects flames within 10 to 80 cm (varies with flame size and sensor model).

Output:

Digital Output (DO): High/Low signal indicating flame presence based on threshold.

Some versions may provide analog output for flame intensity measurement.

Adjustable Sensitivity: Onboard potentiometer to set detection threshold.

Indicator LED: Power and detection status LEDs for easy visual feedback.

Fast Response: Quick detection of flame with minimal delay.

Compact Design: Small size for easy integration into fire safety and monitoring systems.
