Abstract:
Embedded system is a specialized computer system that is part of a larger system or machine. Typically, an embedded system is housed on a single microcontroller board with the programs stored in ROM. Virtually all appliances that have a digital interface -- watches, microwaves, VCRs, cars -- utilize embedded systems.
GSM (Global System for Mobile communications) is an open, digital cellular technology used for transmitting mobile voice and data services. GSM differs from first generation wireless systems in that it uses digital technology and time division multiple access transmission methods. GSM is a circuit-switched system that divides each 200 kHz channel into eight 25 kHz time-slots; GSM supports data transfer speeds of up to 9.6 kbit/s, allowing the transmission of basic data services such as SMS (Short Message Service). Another major benefit is its international roaming capability, allowing users to access the same services when traveling abroad as at home. This gives consumers seamless and same number connectivity in more than 210 countries. GSM satellite roaming has also extended service access to areas where terrestrial coverage is not available.
Our project fire detection and auto intimation is very useful to identify fire and inform to the concerned person very fastly within a short span of short time. Fire detecting sensors are used to detect the fire and the corresponding information is given to microcontroller by means of interfacing circuits. Microcontroller detects the fire and gives the alarm by means of the buzzer which is connected to the controller. At the same time the microcontroller will communicate with GSM modem via serial communication and send SMS is sent to the mobile number which is stored in the controller programming.
Hardware requirement:
- GSM modem
- Microcontroller
- Fire sensor
- Sensor interfacing circuit
- Voltage converter
- 5V power supply
Software requirement:
- Embedded C
- Keil compiler
- Program downloader.
