In this project report as TraiCen load controller (as a switch), a triac MOC3021 driver.GSM use roaming facilities will be used by operators, users can often continue to use their phones when they are in other countries, used, etc. This project trips regulated 5V, 750mA power supply. 7805 and 7812 three-terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to correct the power supply from the secondary transformer 230/12V.

Nowadays there are various electronic devices for remote control of Grid Control. However, the main drawback of these systems is that they can only be operated at close range and even less reliable. So to overcome the above disadvantages, ie we are using a wireless communication technology; GSM (Global System for Mobile communications) is a digital cellular communication system, which has rapidly gained acceptance and market share worldwide. The development of GSM is the first step towards a genuine personal communication system; allow us to communicate everywhere, anytime and with anyone. GSM (Global System for Mobile Communication) is much used because of its simplicity in the transmitter and receiver design can be at 900 or 1800 MHz band to operate fast, reliable and global network.

Conclusion:

GPRS is a medium very well suited to connect small stations of any kind into a process control system. Its biggest advantage is that there is no line of any kind required to connect these stations. Although the quality is not the same as with a privately owned line, it is sufficient for many applications.

In the world of Electronics changes is going on regularly in the technology. As the microcontroller and its features are much more and doing the project in microcontroller at Usha Martin. As the features and application of microcontroller is so much flexible and enriched this project. As the microcontroller have various features for various subsequent requirements.

The ATmega8535 provides the following features: 8K bytes of In-System Programmable Flash with Read-While-Write capabilities, 512 bytes EEPROM, 512 bytes SRAM, 32 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, a byte oriented Two-wire Serial Interface, an 8-channel, 10-bit ADC with optional differential input stage with programmable gain in TQFP package, a programmable Watchdog Timer with Internal Oscillator, an SPI serial port, and six software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or Hardware Reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping. The ADC Noise Reduction mode stops the CPU and all I/O modules except asynchronous timer and ADC, to minimize switching noise during ADC conversions. In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low-power consumption. In Extended Standby mode, both the main Oscillator and the asynchronous timer continue to run.
