The Flame Sensor Module is designed to detect fire or flame sources using infrared light detection. It is based on the LM393 comparator chip, which provides both analog and digital outputs for easy interfacing with microcontrollers. This sensor can detect flame or fire sources within a 760nm – 1100nm wavelength range and is widely used in fire detection systems, robotics, safety systems, and Arduino projects. The module includes a sensitivity adjustment potentiometer that allows users to control the detection threshold according to their project requirements. It is compatible with Arduino, Raspberry Pi, ESP8266, and other microcontrollers, making it ideal for DIY electronics and IoT projects.
