Here we have designed and installed an Automated Flame & Gas Detector with Analyzer. First of all according to the collected information about AFGDA (Automated Flame & Gas Detector with Analyzer) total circuit design has been completed using Proteus software. Flame sensor was used in this project which detects frequency of a room. It annotates the number of turns completed in one minute around a fixed axis. It is used as a measure of rotational speed of a mechanical component. Fire alarm system plays an important role in maintaining and monitoring the safe of all kind environments and situations. However the usability of many existing fire alarm system is well known but could be produce with high cost. Subsequently, it is not affordable for the low income users. The main objective of this project is to make a fire control system with low cost.. The detection system operates as the fire detector. This detection system has components like flame detector, smoke detector, light detector, heat detector etc. This paper discusses the design and implementation of a fire alarm system using the microcontroller which operates the entire system. Any signal from each detector at any level is monitored using monitoring system. The entire system is controlled by microcontroller. The microcontroller is programmed in such way by using C-Programming. From the project done, the system can detects smoke, light, flame, heat etc. sensed by the detector, followed by the monitoring system which indicates smoke, light, flame, heat etc. at that particular level. Finally when the sensors form each level triggered individually, the main buzzer operates and disconnect the AC power supply. Then it shows in the control panel LCD display which area is affected and which is safe. Then it runs the emergency exit motor to escape and the water pump motor to the affected zone to stop the fire. One of the most important actual problems in the gas detection field is that there are strong demands for gas methane leak detection and CO (carbon monoxide) detection to prevent explosions or CO poisoning accidents. In this sense, the present paper describes technical characteristics, test results, and a concluding application for methane and carbon monoxide based gas detection using a sensor which can detect both CO and methane with a single sensing element. The paper presents the detection method as well as the apparatus functional sketch.
