Day 24 Arduino Advent Calendar

Arduino Advent Calendar Day 24 - Flame Sensor

Today we're going to look at the Flame Sensor Module. 

The Flame Sensor Module detects the spectral range of infrared light (760nm to 1100nm) created by open flames. You can obtain sensor readings via the digital and analogue pins. 

A potentiometer controls the sensitivity of the module. 

The module has two LED indicators, one which is a power indicator and another which turns on when a flame is detected.
