GSM BASED SMS CONTROLLER Presented By: 1.JESSU SHIRISH KUMAR (CS12B1018) 2.VEERNAPU SURI BABU (CS12B1039)
Why is this Project ? Can control Appliances even from long range of distances. Ex : As soon as farmer knows power has come , he can power on the motor even from his house.
COMPONENTS 1.GSM MODULE SIM 300 Global system for mobile communication • To describe protocols for 2nd generation and replaced analog Cellular network of 1st gen. Some of the features are • Controlled via AT COMMANDS.
MICRO CONTROLLER Simply a mini computer on a single Integrated circuit with a processor core , memory and programmable input and output Peripherals. Features • 8K BYTES of in system Programmable Flash. • 512 bytes EEPROM. • 1K BYTES SRAM. • Programmable serial USART. • 4.5 to 5.5V operation.

UART(Universal Asynchronous Receiver/Transmitter) • A UART is an individual(or a part of) Integrated circuit used for serial communication over a computer or peripheral device(serial port). • Now Microcontrollers are coming with UARTs. • Serial Communication: Process of sending 1 bit at a time sequentially over a communicational channel.
Working: • SMS sent from phone will be received by GSM modem // by GSM PROTOCOL COMMUNICATION// • AT commands helps microcontroller to get SMS from GSM modem , then reads TEXT of SMS and display it on LCD. //Microcontroller interfaces with GSM modem using UART// • The statues of appliances will change according to the TEXT of SMS.
Uses: • The security for a house can be enhanced. //SMS will be sent to the owner as soon as a bugler broke into house// • Power losses can be minimized. • Things can be made more secure.
