LM393 3-Pin IR Infrared Flame Detection Sensor Module 760-1100nm (Digital Flame Sensor Module)

The LM393 3-Pin IR Infrared Flame Detection Sensor Module is a compact flame sensing module designed to detect infrared radiation emitted by flames in the 760nm to 1100nm wavelength range. It incorporates an infrared-sensitive photodiode and an LM393 voltage comparator to provide a digital output when a flame is detected. The onboard potentiometer allows sensitivity adjustment, making the module suitable for Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other embedded platforms. It is ideal for fire detection systems, flame alarms, robotics, industrial safety monitoring, and educational electronics projects.
