SMS CONTROLLED BRANCH CIRCUIT WITH TIMER AND DIGITAL THERMOMETER

Introduction:

The Short Message Service (SMS) Controlled Branch Circuit with Timer and Digital thermometer is an improvised version of the SMS Controlled Branch Circuit device by the former engineering students of IETI. It is basically a group of smart circuit breakers controlled remotely by a cellular phone. It can automatically switch on or off through text messaging. It also has a built-in timer so you can set the time on the circuit breaker on ....etc

fahrenheit scale digital thermometer is a temperature indicator which displays temperature in fahrenheit scale. it is similar to celsius scale digital thermometer, except a little modification in the microcontroller program. the temperature sensed in celsius scale in the celsius scale thermometer project report is converted into the fahrenheit scale temperature just by using the celsius to fahrenheit conversion formulae.
a digital thermometer can be easily made by interfacing a temperature sensor to the microcontroller at89c51. the temperature ....etc

code for celsius and fahrenheit scale digital thermometer using 8051 microcontroller at89c51

description:
A digital thermometer can be easily made by interfacing a temperature sensor to the microcontroller AT89C51. The temperature sensor used in the project is LM35. The LM 35 IC generates a 10mV variation to its output voltage for every degree Celsius change in temperature. The Output of the temperature sensor is analog in nature so we need an analog to digital convertor for converting the analog input to its equivalent binary output. The ADC ....etc

The telecom department has issued rules for virtual network operators (VNOs) to set up shop in India, offering consumers more choices for voice and data services and allowing telcos additional options to monetise unused airwaves.
After considering the recommendations of Trai on VNO, the government has decided to grant Unified Licence VNO (UL VNO), the guidelines issued by the department said Friday. The Telecom Commission had cleared VNO UL late March.

VNOs are retailers of telecom services who buy bulk minutes from operators and sell th ....etc
