Brief
Flame sensors can be used to detect fire or other light sources with wavelengths in the range of 760 nm to 1100 nm. Flame probes play a very important role in fire fighting robotics competitions, where they can be used as the robot's eyes to find fire sources or soccer balls. It can be used to make fire-fighting robots, soccer ball robots and so on. The flame sensor has a detection angle of 60 degrees and is particularly sensitive to the flame spectrum, with 2 M3 mounting holes to stabilize the module from rotating. This flame sensor can operate at -25 to 85 degrees Celsius for stable and reliable performance. Although this sensor is designed to sense flames, it is not fireproof. Therefore, please keep a distance from the flame when using it to avoid burning the sensor. The port layout of the new version of the analog sensor features the following two improvements. Please refer to our blog [How to Change Data Cable Connector Layout] for instructions on how you may need to adjust the connector layout when using this sensor on an IO expansion board. We will make more improvements for your convenience, so stay tuned.

Sample code
/*
# Product: Flame sensor
# SKU : DFR0076
# Description:
*/
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);
Serial.println(sensorValue);
}Result
When the flame sensor detects an ignition source, the change in value can be observed in the serial port.
