This IR flame sensor module detects flames and infrared light sources in the 760–1,100 nm wavelength range. With a detection angle of approximately 60° and a test range of up to 80 cm (depending on flame size), it provides both digital and analogue output for flexible integration with Arduino, Raspberry Pi, and other microcontrollers.
An onboard potentiometer lets you adjust detection sensitivity, while the LM393 comparator delivers a clean, high-drive digital output signal.
Key Features
- IR Detection – Sensitive to flame spectrum wavelengths (760–1,100 nm)
- Dual Output – Digital (D0, high/low) and analogue (A0, voltage) outputs
- Adjustable Sensitivity – Onboard potentiometer for threshold tuning
- LM393 Comparator – Clean signal with strong driving capability (15 mA+)
- Wide Voltage – Works with 3.3 V and 5 V systems
- Compact – 32 × 14 mm PCB with mounting bolt hole
Specifications
- Detection Wavelength: 760–1,100 nm
- Detection Angle: ~60°
- Detection Range: Up to 80 cm (lighter flame)
- Operating Voltage: 3.3–5 V DC
- Output: D0 (digital switch) + A0 (analogue voltage)
- PCB Size: 32 × 14 mm
Ideal For
- Fire detection and alarm projects
- Firefighting robot competitions
- Safety monitoring systems
Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
