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.
This project is used to find the water level in dam remotely. The water level is increased certainly in dam in case to damage the dam. to avoid that what we do, nowadays a man is used to monitor the water level. And intimate to the higher officials. Our aim of project is to avoid manpower by using one advanced concept with gsm. The water level is increases rapidly due to rain fall. Some three or four sensors is places in the dam. when water level increases the sensor unit is triggered automatically and forward the status to microcontroller. The controller unit checks with that input and send output as text message to the programmed mobile number through gsm modem. By this project each and every variation of water level is informed to that mobile number by controller unit.
