Flame Sensor Working and Its ApplicationsA sensor which is most sensitive to a normal light is known as a flame sensor. That’s why this sensor module is used in flame alarms. This sensor detects flame otherwise wavelength within the range of 760 nm – 1100 nm from the light source. This sensor can be easily damaged to high temperature. So this sensor can be placed at a certain distance from the flame. The flame detection can be done from a 100cm distance and the detection angle will be 600. The output of this sensor is an analog signal or digital signal. These sensors are used in fire fighting robots like as a flame alarm.What is a Flame Sensor?A flame-sensor is one kind of detector which is mainly designed for detecting as well as responding to the occurrence of a fire or flame. The flame detection response can depend on its fitting. It includes an alarm system, a natural gas line, propane & a fire suppression system. This sensor is used in industrial boilers. The main function of this is to give authentication whether the boiler is properly working or not. The response of these sensors is faster as well as more accurate compare with a heat/smoke detector because of its mechanism while detecting the flame. Working PrincipleThis sensor/detector can be built with an electronic circuit using a receiver like electromagnetic radiation. This sensor uses the infrared flame flash method, which allows the sensor to work through a coating of oil, dust, water vapor, otherwise ice.Flame Sensor ModuleThe pin configuration of this sensor is shown below. It includes four pins which include the following. When this module works with a microcontroller unit then the pins areflame-sensorPin1 (VCC pin): Voltage supply rages from 3.3V to 5.3VPin2 (GND): This is a ground pinPin3 (AOUT): This is an analog output pin (MCU.IO)Pin4 (DOUT): This is a digital output pin (MCU.IO)Different TypesFlame-sensors are classified into four typesIR single frequencyIR multi-spectrumUV flame detectorsUV/ IR flame detectorsFeatures & SpecificationsThe features of this sensor include the following. Photosensitivity is highResponse time is fastSimple to useSensitivity is adjustableDetection angle is 600,It is responsive to the flame range.Accuracy can be adjustableOperating voltage of this sensor is 3.3V to 5VAnalog voltage o/ps and digital switch o/psThe PCB size is 3cm X 1.6cmPower indicator & digital switch o/p indicatorIf the flame intensity is lighter within 0.8m then the flame test can be activated, if the flame intensity is high, then the detection of distance will be improved.ApplicationsThese sensors are used in several dangerous situations which include the following.Hydrogen stationsIndustrial heatingFire detectionFire alarmFire fighting robotDrying systemsIndustrial gas turbinesDomestic heating systemsGas-powered cooking devicesThus, this is all about a flame sensor. From the above information finally, we can conclude that the main purpose of this sensor is to reduce the risks which are associated with the ignition. These sensors respond frequently than a smoke or heat detector. Here is a question for you, what are the advantages of the flame-sensor?
