This Gravity analog flame sensor detects fire and infrared light sources in the 760–1,100 nm wavelength range. With a 60° detection angle and analogue output proportional to flame distance, it's widely used in firefighting robots, fire alarm projects, and other safety applications.
The Gravity interface makes wiring simple — a single analogue cable connects the sensor to Arduino, Raspberry Pi, or any 3.3–5 V microcontroller. Two M3 mounting holes allow easy installation on robot platforms and enclosures.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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.
- 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.
