DESCRIPTION
The Flame Sensor Module is used to detect an open flame by detecting light that is in the infrared spectrum as produced by an open flame.


PACKAGE INCLUDES:
Flame Sensor Module


KEY FEATURES OF FLAME SENSOR MODULE:
Detects infrared in the spectrum produced by an open flame
Provides both an analog and digital output with a sensitivity adjustment
3.3 and 5V compatible
This sensor module is primarily used to detect an open flame.  It does this by detecting light that is in the IR (infrared) spectrum which is emitted by a flame.  That spectrum is typically in the range of 700-1100nm.


This module is similar to a regular IR detector, but with a broader detection range.  It can be used as a general IR detector for other applications where a broad detection range is desired.


Outputs
The module has both an analog output and a digital output with sensitivity adjustment on the module.


The Analog output on ‘A0‘ is normally a voltage of approximately 1/2 Vcc when no signal is detected.  The actual voltage level will depend on the setting of the sensitivity pot. If a flame is detected, that output voltage will drop towards ground depending on the strength of the IR detected.


The Digital output on ‘D0‘ is normally LOW.  When IR is detected by the sensor, the output goes HIGH.  The sensitivity adjustment can be used to set the trip point.  LED2 will light when the output goes HIGH.


Module Connections
There is a 4-pin header on the assembly.


1 x 4 Header 


GND / G  = Ground
‘+’ = Vcc (3.3 – 5V)
A0 = Analog output, connects to analog input on uC
D0 = Digital output, connects to digital input on uC


OUR EVALUATION RESULTS:
These modules are interesting for experimenting with flame detection as part of a fire detector setup.  They can also be used to monitor a flame to determine if it has gone out, such as a pilot light.  Commercial fire detection systems often also include light flicker detection to help determine if a flame is present since most sources of IR including sunlight can trigger this module, not just a flame.


The module is straight forward to use.  Hook up ground and Vcc (3.3 or 5V).  A red LED lights when power is applied.  There is a red or green LED2 that lights when IR within the sensor range is being detected.  If that LED is always on, adjust the sensitivity adjustment potentiometer CCW until the LED goes off.  If a match or other flame is then lit and held in front of the sensor, the LED should come on showing that it is being detected.  An IR TV remote can also be used to test the operation of the device by pointing it at the sensor and pressing any button.


The simple program below can be used to monitor both the analog and digital outputs of the device to see how it reacts to the presence of a flame.

int flameDigitalPin = 7;  // Random digital pin for monitoring the digital output
int flameAnalogPin = A0;  // Random analog pin for monitoring the analog output
int digitalValue = 0;     // Variable to hold the returned digital value
int analogValue = 0;      // Variable to hold the returned analog value
