About this product
An infrared flame sensor module built around a 5 mm IR receiver, an LM393 comparator and a trimmer potentiometer for threshold adjustment. It has both analog and digital outputs and detects infrared between 760 and 1100 nm within a 60 degree angle. It operates from 3.3 V to 5.5 V and is used for flame detection projects.
