Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Flame Sensor Arduino Interfacing. Flame sensor is an electronic device which is capable of sensing/detection of fire or a high temperature zone. It gives an indication through an LED attached at its top, just after sensing the fire. These type of sensors are usually used for short ranges. They are able to detect the fire up to 3 feet. Flame sensors is the most common device available in the market these days due to its good results and cost efficiency. You should also have a look at Flame Sensor Library for Proteus.
Flame sensors are available in the market in two types one having three pins and the other having four pins respectively. Both of the sensors can be easily interfaced to any micro-controller. I am using four pin flame sensor in this tutorial. You will see the complete wiring diagram for interfacing flame sensor with Arduino and the complete Arduino source code and its description as well. Flame sensor can detect fire or any other light sources whose wavelength is in the range of 760nm to 1100nm. This device consists of and IR sensor, an LED for indication, operational amplifier circuit and a potentio-meter. The device is sensitive to flame so when it detects the flame it turns on its LED to show an indication. The sensitivity of the flame sensor can be adjusted according to the requirements. It can be used at different places e.g. in offices, home, institutions, industrial applications.
Flame Sensor Arduino Interfacing
Flame Sensor is an electronic device which is used to sense the fire or any other light having wavelength between 700nm to 1100nm. It consists of either three or four pins both of them are compatible with all micro-controllers. It is sensitive to flame and gives the indication for the presence of the flame. It can be sued in homes, offices, industrial applications. Flame sensor along with its pi names are shown in the figure below.
1. Flame Sensor Pins
Flame sensor has four pins with different individual function.
Flame sensor pins are given in the figure shown below.
2. Flame Sensor Pins Description
Each pin has different tasks to perform.
Flame sensor pin descriptions are listed in the table shown in the figure given below.
3. Flame Sensor Working Principle
Flame sensor is very sensitive to flame and other lights.
Its analog output provides real time output voltage on the thermal resistance.
When the temperatures reaches at the certain threshold the output high and low signal threshold adjustable via potentio-meter , Its the task of digital output.
4. Flame Sensor Circuit Diagram
Flame sensor diagram is shown in the figure given below.
5. Apparatus Required for Flame Sensor Interfacing with Arduino
Arduino UNO (Micro-controller)
Light or another flame sensor
6. Flame Sensor & Arduino Pin Connections
Connections between Arduino and flame sensor pins are given in the table shown in the figure below.
The actual circuit diagram for flame sensor interfacing with Arduino.
10. Flame Sensor Applications
Flame sensor has a lot of different applications.
Some of them are given below.
The tutorial Flame Sensor Interfacing with Arduino has explained the entire necessary detail about the flame sensor interfacing with Arduino. If you have any kind of problem you can ask me in comments anytime. I will try my level best to solve your issues. I hope you have enjoyed this tutorial. I will share other informative topics in my upcoming tutorials. Till my next tutorial take care and bye :)
