Heat Flame Sensor – Infrared Flame Detection Module for Fire Sensing Applications The Heat Flame Sensor is a highly sensitive infrared flame detection module designed to detect fire or flame sources within a range of wavelengths typically emitted by fire (760 nm to 1100 nm). This sensor is ideal for fire alarm systems, flame detection in industrial applications, and DIY safety or automation projects. It can detect the presence of a flame or a light source with similar characteristics from a distance, depending on intensity. With both digital and analog outputs, it can easily be interfaced with microcontrollers like Arduino, ESP32, Raspberry Pi, and more.
