The Sensitivity of the Digital pin can be varied using the potentiometer.įlame Sensor Interfacing with LPC2148 Connection Flame Sensor The PCB of this electronic circuit has a potentiometer. in offices, homes, institutions, and industrial applications. The sensitivity of the flame sensor can be adjusted according to the requirements. The device is sensitive to flame so when it detects the flame it turns on its LED to show any indication. This device consists of an IR sensor, an LED for indication, an operational amplifier circuit, and a potentiometer. Note: If you are using a 4-Pin sensor, you need to use D0 Pin to work with this example.Ī flame sensor can detect fire or any other light sources whose wavelength is in the range of 760nm to 1100nm. I am using the three-pin flame sensor in this tutorial. Both of the sensors can be easily interfaced with any microcontroller. So in this tutorial, we are going to use an IR flame detector.įlame sensors are available in the market in two types one having three pins and the other having four pins respectively. Since more than 90% of the flame’s total radiation is infrared, these detectors receive ample radiation of quite high intensity and will operate with either very weak or very hot flames. Optical flame sensors are divided into many groups depending on which range of the total radiation band they are designed to detect: Flames are known to emit electromagnetic radiation in the infrared (IR), visible light, and ultraviolet (UV) wavelengths depending on the fuel source. Today’s flame detectors utilize optical technologies to detect flames. Flame Detector or Fire DetectorĪ flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.

Ionization of the atmosphere in and around the flameįlame detection systems have been developed to incorporate several of these characteristics.

Emission of light (infrared or ultraviolet).

Production of the by-product of combustion.

Characteristics of flameĪll flames have certain characteristics in common that include:

So if we find the flame, then we can also find the fire. The flame is the visible portion of the fire. The rapid detection of a fire and its control can save several thousand lives, thousands of injuries, and millions of dollars in property loss each year. Fire is, of course, destructive, and the smoke from a fire creates a toxic, dangerous atmosphere. While fire can be our friend in some instances, it can be our worst enemy when it’s uncontrolled and allowed to continue through a building. LCD Module (To print the Sensor output)įire is one of the most dangerous events possible somewhere in the world, one occurs every minute of every day.Before starting this tutorial we should know the below topics.
