: 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).
