A flame sensor is used to detect fire or flame in the wavelength range of 760nm-1100nm from the light source.
The flame sensor is easily damaged to high frequency that why this sensor can be placed at a certain distance from the flame.
This sensor detection can be 100cm distance and angle will be 600 and the output will be a digital or analog signal.
Pin1 (VCC pin): Voltage supply rages from 3.3V to 5.3V
Pin2 (GND): This is a ground pin
Pin3 (AOUT): This is an analog output pin (MCU.IO)
Pin4 (DOUT): This is a digital output pin (MCU.IO)
Working of Flame Sensor
This detector can be constructed with an electronic circuit using a receiver like electromagnetic radiation.
Flame sensors employ the infrared flame flash method. It allows the sensor to work through a coating of oil, dust, water vapor, and ice.
A flame sensor is based on the YG1006 sensor which is a high-speed and high-sensitive NPN silicon phototransistor.
Application of Flame Sensor
Flame sensors are used in different places like Hydrogen stations, Industrial heating, Fire Detection, Fire alarm, Fire fighting robot, Drying systems, Industrial gas turbines, Domestic heating systems, and Gas-powered cooking devices.
