For years, infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now, infrared LED has evolved into a system of significantly greater importance and use. Throughout the world, it is now being used to transmit voice, television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result, millions of dollars are being spent to put these light wave communication systems into operation.

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.

This project creates a wireless sensor actuator network for a scaled Heating, Ventilation & Air Conditioning controller rig that exists in Upson 126 in Professor Brandon Hencey’s Lab. This project is meant to facilitate data collection from the HVAC rig to Matlab software on a main PC by taking the full advantages of the wide spreading Xbee modules that operate on Zigbee protocol. This collected data helps to do further data analysis, model calibration and optimization without the need to wire a single component to the computer.

Cell phones and radio receivers are used everywhere these days. It’s great to be able to call anyone anytime. But unfortunately, restaurants, movie theatres, concerts, shopping malls and churches all suffer from the spread of cell phones because not all cell-phone users know when to stop talking. While most of us just grumble and move on, some people are actually going to extremes to retaliate. FM Jammer can be one of the solutions to this problem. Continue reading Report on FM Transmitter as a Jammer with Circuit Diagram
The platform, using dual element Pyroelectric Infrared Sensors (PIR) sensors, rotates itself independently to direct air flow to whatever position a person moves to. In addition, the fan includes another setting that allows precise rotation between two people. These modes are selectable by the user. The running mode is displayed on an LCD. Continue reading A Human Tracking Fan System
In general, we have no correct mechanism to know the parameters like the route in which a cab (vehicle) has travelled, where was it at a particular instant of time, with what speed did it travel at that place and time and did it go to the desired place or not, we don’t have a option rather than to believe the driver. The problem arises when the driver doesn’t give us the exact authentic information. If we want a cab (vehicle) to go to certain place, via certain route, with certain speed within in certain time, later when we access the information about the journey, we have to simply depend up on the driver for the information of the cab and the driver may not give us the exact information about the journey and could use the cab (vehicle) for his personal use.
The GPS BASED CAB MONITORING SYSTEM answers to all the problems raised above. We can know the parameters like the distance travelled, time of the journey, speed of the cab (vehicle), route adopted by the driver with out being dependent on him. We make use of a GPS modem, Multimedia card, Micro controller and a wireless network (RF transceiver) and PC where the map of the route is given through Google Earth.
Data logging mechanism is used here the data logging is done from GPS receiver to the Multimedia card by interfacing them with a micro controller. The stored data in the Multimedia card is sent to the PC through wireless (RF transceiver). The usage of wireless network may increase the hardware complexity but avoids the usage of the cables which is an irritating task to connect when the data needed to be transmitted to the pc, which is used analyze the data graphically, using a software called Google Earth map.
