DFRobot Gravity Analogue Flame Sensor for Arduino, 22x30mm

DFRobot Gravity Analogue Flame Sensor for Arduino

The DFRobot Gravity Analogue Flame Sensor detects fire or other light sources in the 760nm to 1100nm bandwidth. It is ideal for fire-fighting robots to locate a fire source quickly. The sensor’s probe angle of 60° and detection range from 20cm (at 4.8V) to 100cm (at 1V) make it suitable for a wide range of safety and robotics applications. With an analogue interface and an operating voltage of 3.3–5.5V DC, this sensor can be easily integrated with most microcontrollers, including Arduino development boards.

The sensor features a plug-and-play Gravity 3-pin interface, which simplifies wiring and reduces development time. Its compact 22x30mm board size makes it suitable for embedded designs, electronics education, and IoT projects. The temperature range of -25°C to +85°C ensures reliable performance in various environments.
