Introduction
The flame sensor can be used to detect fire or other wavelength at 760 nm ~ 1100 nm light. In
the fire-fighting robot game, the flame plays an important role in the probe, which can be used as
the robot's eyes to find fire source or football. It can make use of fire-fighting robots, soccer
robots.
Flame sensor probe angle of 60 degrees, the special sensitivity of the flame spectrum, two M3
mounting holes to stabilize the module will not spin.
The flame sensor's operating temperature is -25 degrees Celsius to 85 degrees Celsius, in the
course of the flame it should be noted that the probe distance from the flame should not be too
close inorder to avoid damage.
The new version of analog sensor port pin mapping has been changed as the following two
features.Please check
the tips for changing sensor cable pin mapping
while using the I/O
Expansion shield. We will continue to update. For the inconvenience caused, please understand.

Sample Code
/*
# Product: Flame sensor
# SKU
: DFR0076
# Description:
# When flame sensor detected flame, the data will be read by the serial.
*/
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);
Serial.println(sensorValue);
}
Result
When the flame sensor detects the flame in the numerical change can be observed in the serial
monitor.
FAQ
Q1.
Some general Arduino Problems/ FAQ/ Tips, very good to know.
A. Clike the topic link on DFRobot Forum.
Q2.
Why my two flame sensors get different readings when to detect the same flame?
A. It's normal. As an analog sensor, the readings would be effected by flame intensity, flame
position (angle & distance).
Q3.
My flame sensor detects a flame without a flame present. At my desk it was reading
values below 20, in my classroom students read value up to 800 without a flame present.
A. The range of Spectral Bandwidth of the sensor is: 760nm to 1100nm, so it would detect any
light whose Spectral Bandwidth is within 760‐1100nm. After test, we found it can be effected
not only by flame, but also by infrared radiation (Analog read: 900), neon lamps in classrooms
(Thanks to Richard) and it can even be effected by phone's flash (Analog read: 50). Generally, in
our office, it outputs 0V (analog read: around 10). This can be found in its datasheet.
