ECE Mini Projects 2011 2012 2013

 

Prepaid Energy Meter

Uses an 8051 and 89c2051.8051 as main microcontroller.89c2051 as smartcard and in it maximum units to be used is programmed.This data is given to 8051.8051 is connected to a digital energy meter.8051 is programmed to decrement the maximum units as a response to the information from digital energy meter.There is a buzzer to warn the user.When maximum use is made relay is cut off.Then we have to reset both microcontollers ...........>>>>>Read More

 

High Bandwidth Low Noise Amplifier with improved stability over Radio Frequency range

The measuring appliance amplifier is a double-end input differentiator amplifier, besides the high accuracy, the high stable characteristic, its output zero reference voltage may establish willfully through the REF base pin's voltage, this adjusted zero for us to float has provided the possibility. The AD620 input end has reaches as high as 109O the input impedance; Input offset voltage 30uV, output offset voltage 400uV. The input bias current is very low, usually is highest in 0.5nA does not surpass 2nA; When ...........>>>>>Read More

 

Home Automation Using DTMF Decoder

In this project we present a home automation system using telephone lines. The system consists of two subsystems. One is the remote control system. The other one is the phone monitoring system. The remote control system use the dual tone multi-frequency signals to control the operations of various appliances. The hardware and software are designed based on the standard telephone system. The phone monitoring system provides convenient services for the user to better monitor the usage ...........>>>>>Read More

 

Infrared Remote Control

In modern electronics, electronics remote control system is well known system. Infrared Remote Control kit's available in the market are quite expensive and it some one wishes to assemble one, their IC's may not be easily available. More over for simple ON-OFF function such as controlling a lamp or fan we do not need very complex circuit. The IR remote control circuit using photodiode and phototransistor sensor suffer from major drawback of being affected by ambient light and a very low range. ...........>>>>>Read More

 

Variable Power Supply

A variable power supply technique for use with a high efficiency line driver uses a signal peak amplitude to determine a start of a rise time for a power supply to begin supplying operating voltage to the line driver. This ensures that the voltage supplied to the line driver essentially tracks the output signal. A slew start delay circuit detects when the signal rises above a level that can be supported by a current power supply, ...........>>>>>Read More
