ABSTRACT
This project is titled design and construction of an automatic fire alarm. Fire alarm is an electronics device that is stored in a building to detect the presence of fire accident. An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off-premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.
The aim of this project is to design and construct a fire alarm for a building that will detect the presence of fire accident in a building using SMS Alert system, it uses LM35 Temperature Sensor and MQ2 for Smoke sensing and 16×2 LCD is used to display temperature and Smoke Level,
CHAPTER ONE
1.0 INTRODUCTION
In modern society, it is impossible to imagine house or building without a fire accident detector. Modern houses require a continuous installation of fire detector. Not only industry, but also in the household. Take the case of a duplex that experience a fire accident without a detector that means everything in that building will get burnt even human beings. But in a case whereby fire alarm is installed that means every one in that building will be alerted and also fire security bodies will also be informed for quick security action. The same thing can also happen to our offices and industries. In order to notify residence of any building in the presence of fire accident, a fire alarm system is used.
An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off-premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.
1.1 OBJECTIVE OF THE PROJECT
The objective of this work is to construct a device that will detect the unwanted presence of fire by monitoring environmental changes associated with combustion using GSM SMS Alert system, it uses LM35 Temperature Sensor and MQ2 for Smoke sensing and 16×2 LCD is used to display temperature and Smoke Level.
1.2 SIGNIFICANCE OF THE PROJECT
- The primary advantage of a home fire alarm system is increased reliability and the ability to place alarms and bells exactly where needed. However, the reason most people have them is that they wanted a burglar alarm system and the cost of adding fire alarm features to a residential burglary system is relatively small.
- This device disconnects Electrical Supply as soon as Fire is detected.
- Sends Fire Alert SMS with Temperature and Smoke Level to Given number.
- Makes Loud Sound using buzzer to alert about fire. Uses Standard MQ2 Smoke Sensor and LM35 Temperature Sensor.
- Low Cost This project is very useful for Monitoring of temperature, smoke level, It gives SMS Alert as soon as fire is detected. In this project GSM Modem, MQ-2, LM35 are main parts
1.3 SCOPE OF THE PROJECT
GSM, Microcontroller Based Fire detection and SMS Alert system, it uses LM35 Temperature Sensor and MQ2 for Smoke sensing and 16×2 LCD is used to display temperature and Smoke Level, Over limit set points are set inside the program you can modify it as per your requirements, It Sends SMS when set limits are crossed through GSM modem that is attached to Serial Rxd and Txd Pins, Set your mobile number inside the code in SendSMS subroutine. It generates Sound When Fire is detected for alerting.
1.4 APPLICATIONS OF THE PROJECT
- SMS based Fire Alarm system are very useful in remote locations where human interaction is limited. Such systems are useful in mines, industrial areas, factories etc.
- Night Owl – We all know owls don’t sleep during night. SMS based Fire Alarm system helps to monitor locations and alert during fire that occurs in night time.
- Quick Actions to shut down Fire – 90% of fire damages occur due to lack of early fire detection. A fire attack is usually silent and people will know about fire only when it has spread across a large area. SMS based Fire Alert system gives warning immediately to multiple mobile numbers and hence remedy actions can be taken quickly. This helps to prevent major damages and losses created by a fire accident.
CHAPTER FIVE
5.1 CONCLUSION
In conclusion, there are several options for a building’s fire detection and alarm system. The ultimate system type, and selected components, will be dependent upon the building construction and value, its use or uses, the type of occupants, mandated standards, content value, and mission sensitivity. Contacting a fire engineer or other appropriate professional who understands fire problems and the different alarm and detection options is usually a preferred first step to find the best system.
