Reasons of Major Losses
• Lower quality of Fire Detection System• Communication gap among the buildings and Nearest Fire
Service Stations• Lack of Fire Extinguishers• Absence of Emergency Systems

Project Overview:
• A remote SMS system to communicate immediately with nearest fire stations, local PS, local hospitals and other necessary places
• A emergency light system in case of power failure

Required chips
• ATMEGA32A• LM35 (Heat Sensor)• LM324 (Op-Amp)• 7404 (Not Gate)• SIM900 (GSM Module)

Remote SMS System
• The GSM module (SIM 900) is interfaced with ATMEGA32A in the total system
![Page 11: Fire protection system](https://reader035.vdocuments.us/reader035/viewer/2022062308/55c14201bb61ebc37c8b45c2/html5/thumbnails/11.jpg)
Sensing The Fire
• A heat sensor (LM35) is used to detect room temperature• A comparator circuit is used to compare the output voltage of
LM35 with a given reference voltage• If the output is above certain level, it takes the decision that a fire
incident has occurred

SOS
As the fire has been detected, the module will automatically send SMS to necessary persons and places

Emergency Light System
• Powered by a rechargeable DC battery• If the main power goes off, the emergency lights
automatically turn on• Other times, the battery is being charged and kept nearly
100% charged

Cost Estimation
• GSM Module- Tk. 2300• Transformer (220-6V)- Tk. 65• Microchip (ATMEGA32A)- Tk. 200• Heat Sensor (LM35)- Tk. 45• DC Battery (2 pcs)- Tk.50• Miscellaneous- Tk. 130
• Total Cost- Tk. 2790
In case of MASS PRODUCTION, total cost can be decreased to Tk. 2000 (estimated)

Limitations
• LM35 is very sensitive, so in case of other temperature arising incidents, the system can turn on.
• The output of LM35 is in mV range (10 mV/◦C), so minor noise can activate the system

Future Development
• Inclusion of fire alarm• Automated Fire Extinguishers in sensitive places
![Page 18: Fire protection system](https://reader035.vdocuments.us/reader035/viewer/2022062308/55c14201bb61ebc37c8b45c2/html5/thumbnails/18.jpg)
Cautions
• Both GSM Module and Microchips are voltage sensitive, minimum increase can harm these devices
• GSM module is temperature sensitive• Total system (except the LM35) should be installed in a
neutral place
