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 single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
