Overview

The flame sensor can detect flame and infrared light source with wavelength ranging from 760 nm to 1100 nm.

It uses LM393 comparator chip which gives clean, stable digital signals and with driving ability of 15 mA.

It is a very efficient flame detector that can be used in fire alarms and other fire detecting devices.

This sensor should maintain a certain distance from the flame to prevent damage due to high temperature.
