Abstract:
This project is about designing a fire alert and gas leakage warning system via GSM. In this
project microcontroller system, sensors, GSM module and several other devices are used by me.
The detector is based on the commercial gas sensor from Hanwei Electronics Co. Ltd,
Temperature Sensor by National Semiconductor and LCD alphanumeric display. This system
uses Microchip microcontroller as a tool to collect input data, process and release output data.
Microcontroller system is connected with input and output devices consist of LCD display and
GSM module. This project will be a reference material to the future student or consumer in
order to understand usage of a microcontroller and make use of its features. Reprogramming
function of the microcontroller is enabled in order to allow user to explore and experience how
to program a microcontroller. Output and input device are presented in such interactive way to
actually show how microcontroller does the controlling part of the project.
Description:
Fire accident is a common incident in factories, houses, markets in every country. Due to poor
fire extinguishing arrangement, lack of adequate fire alarm and emergency exit, it increases
death and wreck. When it comes to security issues, we cannot take it for granted. Security is the
level of protection against danger and loss. Nowadays, in a world that full of technology, people
needs the help of technology to provide early warning alert to ensure they have enough time to
avoid danger. In designing this project, the dangerous sources that have been highlighted are
about gas leakage and fire. This is because both of these can become a huge disaster if the
security procedure is not taken early. To minimize fire accident our project will act as a sentinel
which is control from a central console room. For detection we used a high sensitive smoke
detector by which microcontroller will get high pulse at input pin which is preprogrammed for
our desired output signal.
