Circuit Schematic Aircraft Hangar Fire Alarm System using Flame Detector and Arduino Uno

Eltronicschool. - It is very important to protect aircraft hangar from fire with give the fire alarm system when the fire detected by flame detector installed. There are many flame detector used in fire alarm system likenear IR array detector, ultraviolet detector, infrared (IR) detector, UV/IR detector, Infrared thermal cameras etc.

In here we will give you one circuit schematic connection from aircraft hangar fire alarm system using flame detector and Arduino Uno. The flame detector in this circuit, we used infrared (IR) detector and Arduino Uno to manage data from flame detector.

Circuit schematic like in Figure 1 above is Circuit Schematic Aircraft Hangar Fire Alarm System using Flame Detector and Arduino Uno. Flame sensor module used to detect the light and op-amp to control the sensitivity of flame detection. In aircraft hangar, this flame sensor is used to detect fire and provide HIGH signal upon the detection. Arduino Uno is used to reads the signal and provides alert by turning on buzzer and LED.

Flame Sensor 

A flame detector is one of the sensor that designed to detect and respond the presence of a flame or fire. In this aircraft hangar fire alarm system we used IR flame detector based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. This sensor module can detect infrared light with a wavelength ranging from 700nm to 1000nm and its detection angle is about 60°.

This sensor module consists of a photodiode (IR receiver), resistor, capacitor, potentiometer, and LM393 comparator in an integrated circuit. We can adjust the sensitivity by varying the on board potentiometer. We need voltage between 3.3v and 5v DC for this sensor, with a digital output. Logic high on the output indicates presence of flame or fire. Logic low on output indicates absence of flame or fire.

Working of Flame Sensor with Arduino

Arduino Uno is a open source microcontroller board based on ATmega328p microcontroller. It has 14 digital pins (out of which 6 pins can be used as PWM outputs), 6 analog inputs, on board voltage regulators etc.

Arduino Uno has 32KB of flash memory, 2KB of SRAM and 1KB of EEPROM. It operates at the clock frequency of 16MHz. Arduino Uno supports Serial, I2C, SPI communication for communicating with other devices. The table below shows the technical specification of Arduino Uno.

  1. Howdy, i read your blog occasionally and i own a similar one and i was just curious if you get a lot of spam responses? If so how do you protect against it, any plugin or anything you can suggest? I get so much lately it’s driving me crazy so any support is very much appreciated. printed circuit board

  2. I think this is an informative post and it is very useful and knowledgeable. therefore, I would like to thank you for the efforts you have made in writing this article. ציוד כיבוי אש בבאר שבע
