Flame Sensor - 850nm Photo Transistor

This flame sensor is ideally used in fume cabinets, industrial heaters, or any other heat emitting device. It is able to detect the infrared light emitted by a flame or fire and discarding other light sources.

If you wish to receive Infrared data from a remote, it is suggested to use the VS1838 Infrared Receiver.

Flame Sensor Specs:

• Open current voltage: 0.39V
• Reverse voltage: 32V
• Short-circuit current: 35 µA
• Reverse light current: 25 to 35 µA
• Reverse dark current: 5 to 30nA
• Total capacitance: 10pF
• Rais time and fall time: 45ns
• View angle: 80 degree
• Wavelength sensitivity: 850nm

/* Flame Sensor - Analog Output - Test Code */

void setup() {

Serial.begin(9600); //baud rate @ 9600

}

void loop() {

int sensorValue = analogRead(A0); // read sensor output value @ A0

Serial.println(sensorValue); // display it on serial monitor
