Technical Overview

The Flame & Fire Detection Sensor Module by FamePhase Electronics is an ultra-fast, high-sensitivity optoelectronic hazard control card designed for fire-fighting robotics, automated flame suppression, and industrial burner safety networks. Sourced for exceptional reliability, it incorporates a high-speed NPN photodiode spectrum receiver optimized to detect infrared wavelengths between 760 nm and 1100 nm. Integrated with an LM393 voltage comparator and an adjustable sensitivity potentiometer, the module yields dual outputs—raw analog voltage for distance-to-flame measurement and precise digital TTL triggers for instant alarm execution on Arduino, ESP32, and Raspberry Pi platforms.
