Bluetooth Based Data Logger

The main aim of this project is to develop data logging system using Bluetooth. Say for e.g.: think we are designing the Blue tooth based remote reading of the house energy meter. In this project the user can access and download the data from his computer remotely using the blue tooth enabled mobile. In the receiver side there will be hard ware with microcontroller, Bluetooth Transmitter and Receiver. Continue reading Bluetooth Based Data Logger

Automated Beverage Vending Machine

An automated beverage vending machine comprises of a microcontroller which is programmed to instruct the system to serve the beverage. Machine will activate when the user insert a five rupee coin into coin slot. This coin will be detected by an IR-sensor and send a signal to microcontroller. The machine comprises of cylinder controlled by microcontroller. A fixed volume beverage is filled in the main container. The beverage is poured in the glass through tap which opens and closes after fixed time period and only activated when container is filled. Hence, the user gets the beverage demanded by him by fully automated technique. Continue reading Automated Beverage Vending Machine

Automatic Room Light Controller with Visitor Counter

This Project “Automatic Room Light Controller with Visitor Counter using Microcontroller” is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one. The light will be only switched OFF until all the persons in the room go out. The total number of persons inside the room is also displayed on the seven segment displays. Continue reading Automatic Room Light Controller with Visitor Counter

Microcontroller based Automatic Power Factor Controlling System

The Embedded Technology is now in its prime and the wealth of knowledge available is mind-blowing. Embedded technology plays a major role in integrating the various functions associated with it. This needs to tie up the various sources of the Department in a closed loop system. This proposal greatly reduces the manpower, saves time and operates efficiently without human interference. This project puts forth the first step in achieving the desired target. With the advent in technology, the existing systems are developed to have in built intelligence. Continue reading Microcontroller based Automatic Power Factor Controlling System

Scalability of Ad Hoc Dynamic Spectrum Access Networks

Abstract :-

Dynamic Spectrum Access allows wireless users to access a wide range of spectrum which increases a node’s ability to communicate with its neighbors, and spectral efficiency through opportunistic access to licensed bands. Our study focuses on the scalability of network performance, which we define in terms of network transport capacity and end-to-end throughput per node, as the network density increases.

Model-Based Approach to Demodulation of Co-Channel MSK Signals

Abstract :-
Co-channel interference limits the capacity of cellular systems, reduces the throughput of wireless local area networks, and is the major hurdle in deployment of high altitude communication platforms. It is also a problem for systems operating in unlicensed bands such as the 2.4 GHz ISM band and for narrow band systems that have been overlaid with spread spectrum systems.
