Flame Sensor : Working & Its Applications

• 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.

1. 1. Pin1 (VCC pin): Voltage supply rages from 3.3V to 5.3V
   2. Pin2 (GND): This is a ground pin
   3. Pin3 (AOUT): This is an analog output pin (MCU.IO)
   4. 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.
