Description

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.

Description

Circuit schematic like in Figure 1 and Figure 2 above is transmitter and reciever of ultrasonic fuel level indicator based on Arduino. There are two parts of this circuit, these are transmitter and reciever with the same component in tow part is nRF24Lo1 wireless Tx/Rx module.

How it works

Accordingly Homemade Circuit site describe there are a pair of ultrasonic sensors in the module. One senor sends the ultrasonic frequency or the wave towards the fuel surface. The waves collide with the fuel surface and reflect back towards the module. The reflected ultrasonic waves are captured by the second sensor unit, and sent to the Arduino.

The Arduino compares the reflected ultrasonic time with the reference time of the tank "full height" and creates an estimation of the instantaneous height or the level of the fuel.

The information is then encoded and forwarded it to the nRF24L01 wireless module. The nRF24L01 module finally converts the code into RF signal and transmits it into the atmosphere for the receiver unit to capture the signal.

The general syntax of this function is pulseIn(pin, value, time) where pin is the name of the pin, value is either HIGH or LOW and time is time for which the function to wait for a pulse. The function returns zero if there is no valid pulse with in the specified time. The pulseIn() function can count pulses with time period ranging from 10 μS to 3 minutes.

Component Part

Description

Circuit schematic like in Figure 1 above is Circuit Schematic Arduino-based Front Office Visitor Alarm. Electronicsforu site describe that Arduino Uno operates off a 9V DC power supply. It is based on ATmega328 microcontroller and has 14 digital input/output pins, six analogue input pins, a USB connection for programming the onboard microcontroller, a 9V-12V DC power jack, an ICSP header and reset button. It is operated with a 16MHz crystal oscillator and contains everything needed to support the microcontroller.

Reed switch S1 is connected to digital pin 2 of Arduino as the input. PZ1 and LED1 are connected to digital pins 7 and 8, respectively, as outputs. LED1 is connected through a 220-ohm resistor.

Initially, when the door is closed, the magnet on the door is close to the reed switch (normally-open type) on the door frame and hence the reed switch is closed. So pin 2 of Arduino is ‘high.’

When the door is opened, the reed switch opens and pin 2 of Arduino becomes ‘low’ through a 10-kilo-ohm pull-down resistor. This turns on piezo buzzer PZ1 and LED1. After a few seconds, PZ1 and LED1 automatically turn off.

The software (office_visitor.ino) for this project is written in Arduino programming language. Arduino Uno is programmed using Arduino IDE software. ATmega328 on Arduino Uno comes with a bootloader that allows you to upload new code to it without using any external hardware programmer.

Description

Accordingly Henrysbench blog that also published this project describe that the Arduino analog input is limited to a 5 VDC input.   If you wish to measure higher voltages,  you will need to resort to another means.  One way is to use a voltage divider. It is fundamentally a 5:1 voltage divider using a 30K and a 7.5K Ohm resistor.

Keep in mind, you are restricted to voltages that are less than 25 volts.   More than that and you will exceed the voltage limit of your Arduino input.
