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.

/*
# 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.ClikethetopiclinkonDFRobotForum.
Q2. Why my two flame sensors get different readings when to detect the same flame?
A.It'snormal.Asananalogsensor,thereadingswouldbeeffectedbyflameintensity,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.
