Description
KY-026 Flame Sensor Module
KY-026 Flame Sensor Module detects infrared light emitted by fire. This module has both digital and analog outputs and a potentiometer to adjust the sensitivity. Commonly used in fire detection systems.
Compatible with Arduino, Raspberry Pi, ESP32 and other microcontrollers.
KY-026 SPECIFICATIONS
This module consist of a 5mm infra-red receiver LED, a LM393 dual differential comparator, a 3296W trimmer potentiometer, 6 resistors,2 indicator LEDs and 4 male header pins. The board features an analog and a digital output.

KY-026 ARDUINO CODE
In this Arduino sketch we’ll read values from both digital and analog interfaces on the KY-026, use a lighter or a candle to interact with the flame detector module.
The digital interface will send a HIGH signal when fire is detected by the sensor, turning on the LED on the Arduino (pin 13). Turn the potentiometer clock-wise to increase the detection threshold and counter-clockwise to decrease it.
