KY-026 Flame Sensor Module

Description:
The 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. It is also compatible with Arduino, Raspberry Pi, ESP32 and other microcontrollers.
It is based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor.
The ky-026 flame sensor module circuit board has 4 male connector pins, they are -
AO: Analog Out
G: GND (Ground)
+: Vcc (+3.3V to +5V)
DO: Digital Out

This sensor has three functional components on its circuit board: The front sensor unit, which physically measures the environment and outputs it as an analog signal to the second unit, the amplifier. This amplifies the signal depending on the resistance set on the rotary potentiometer and sends it to the analog output of the module.

Application:
Flame alarm
Fire immunity
Fire station systems
