IR Flame Sensor Module

Detect flames and infrared light sources with this compact IR flame sensor module. Sensitive to wavelengths between 760nm and 1100nm, it can detect a lighter flame at distances up to 80cm with a 60-degree detection angle.

Features both digital and analog outputs, with adjustable sensitivity via the onboard potentiometer. Built around the reliable LM393 comparator for clean signal output.
