gsm based home automation using 8051 microcontroller code

The acronym of the GSM modem is Global System for Mobile Communications, it is a wireless communication module, used to make a computer or any processor to communicate over a network. This modem uses a variation of TDMA(Time Division Multiple Access) and is the most commonly used of the digital wireless telephony technologies like TDMA, GSM and CDMA.A GSM modem needs a SIM card to operate through a n/w range subscribed by the network operator. This modem can be connected to a computer ....etc

General Description


Abstract
The ADC0801, ADC0802, ADC0803, ADC0804 and ADC0805 are CMOS 8-bit successive approximation A/D converters that use a differential potentiometric ladder similar to the 256R products. These converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. These A/Ds appear like memory locations or I/O ports to the microprocessor and no interfacing logic is ne ....etc
