INTRODUCTION
Mobile Phones and the related technologies are becoming more and more ubiquitous. Various technical arenas in the field of Telecommunication and Embedded Systems have come very near to the common people. The number of people with cell phones is on the rise. A day will come, somewhere in the near future, when a mobile phone is referred to in the same class of Food, clothing and shelter. Improvements in the Networking technologies have fostered growth of very dense networks. Land li ....etc

Speed Control of 3-Phase Induction Motor Using PIC18 Microcontrollers
INTRODUCTION
Induction motors are the most widely used motors forappliances, industrial control, and automation; hence,they are often called the workhorse of the motion industry.They are robust, reliable, and durable. When poweris supplied to an induction motor at the recommendedspecifications, it runs at its rated speed. However,many applications need variable speed operations. Forexample, a washing machine may use different speedsfor each wash cycle. Histor ....etc

Implementing a PID Controller Using a PIC18 MCU


INTRODUCTION
Continuous processes have been controlled by
feedback loops since the late 1700’s. In 1788, James
Watt used a flyball governor on his steam engine to
regulate its speed. The Taylor Instrument Company
implemented the first fully functional Proportional,
Integral and Derivative (PID) controller in 1940.
Although feedback control has come a long way since
James Watt, the basic approach and system elements
have ....etc

INTRODUCTION
1.1 MOTIVATION
Electronic mail”often abbreviated as e-mail or email”is a digital communication mechanism, designed primarily for human use, which consists of message content, an author and one or more recipients. It is a facility typically added quickly to any online communication service, whether a single machine or a network. In some other words Email is simply the shortened form of electronic mail, a protocol for receiving, sending and storing electronic messages. Email has gained ....etc

ABSTRACT
The objective of this project is to design an embedded system which can control appliances remotely. This project is designed to study the basic implementation of DTMF (Dual Tone Multi Frequency).
The DTMF signal is composed of high frequencies & low frequencies. Each key is assigned a low frequency and a high frequency. When a particular key is pressed, the frequencies those are specific to that particular key are transmitted. Therefore, no two keys will have a same set of low & high frequencies ....etc

1. Introduction:-
This Project will turn on the lights of the room automatically when a first person comes in the room and will turn off the lights when last person leave the room.
2. Working:-
In this project we are using Microcontroller board, Relay board, LCD, Buzzer, Power supply board and LDR based two counter sensors(one for in counter and second for out counter).
In this project our in counter sensor is placed outside from the gate and out counter sensor is placed inside the room. When first person e ....etc

microcontroller based power monitoring for 600KVA BATTERY BACK UP
1.INTRODUCTION
The microcontroller-based power monitoring system is an electronic device used to continuously monitor the parameters of power such as voltage, current, frequency, etc at the various points of an electric or electronics devices. The entire system is controlled by the microcontroller (80C31) and it is the real time monitoring of various parameters. Thus the name REAL TIME MONITORING OF HIGH CAPACITY (400KVA-600KVA) BATTERY BACK UP SYSTEM. This system is an 8-chan ....etc

INTRODUCTION
1.1 Project Description:
The microcontroller is at the heart of this project. The perimeter of the secured area is monitored by surveillance cameras and is supported by an electric fence. In the view of power saving we have enhanced the electric fence with PIR sensors. The electric fence also uses solar panel the above mentioned advantage The PIR sensor works on the principle of voltage bucking configuration.
These sensors detect motion within a field of view that requires a line of sight; they cannot ....etc
