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.

The 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 are

• 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)

Different Types

Flame-sensors are classified into four types

• IR single frequency
• IR multi-spectrum
• UV flame detectors
• UV/ IR flame detectors
