IR Infrared Flame Sensor

The IR Infrared Flame Sensor Module is designed to detect open flames and light sources emitting wavelengths in the 760 nm – 1100 nm range. Built around a high-sensitivity photodiode and an LM393 comparator chip, it provides fast, reliable detection for fire alarms, safety automation, and firefighting robotics projects.

Key Features:

• Detection Spectrum: 760 nm to 1100 nm infrared wavelength detection range.

• Detection Angle: ~60° wide spectrum sensitivity.

• Adjustable Sensitivity: Onboard potentiometer for custom threshold tuning.

• Dual Output / Digital Output: High/Low digital signal output (and optional analog output depending on module pinout) for easy microcontroller interfacing.

• Operating Voltage: 3.3V – 5V DC working voltage (compatible with Arduino, ESP32, STM32, and Raspberry Pi).

• Onboard Indicators: Dedicated LEDs for power status and signal output trigger.

Applications:

• Firefighting robots and automated fire suppression systems

• Smart home safety and early fire detection alarms

• Industrial flame and ignition monitoring
