ULTRA-SONIC DISTANCE METER. Introduction to Ultrasonic Distance Meter The project Ultrasonic Distance Meter is a very interesting and useful project for many industrial applications. In this project we have used the ultrasonic waves to measure the distance in between two points. The basic principal is based on the speed of ultrasonic waves in open air. We have used a microcontroller AT89S51 to transmit and receive ultrasonic waves through 40 KHz ultrasonic receiver and transmitters. By measuring

"Electrical Energy Consumption" Sustainability and electricity Where does electricity come from? Most people use electricity and see it as something that is infinite and probably don’t give a second thought about its source. This is quite understandable‚ considering electricity looks clean; it doesn’t cause any noise pollution or direct air pollution. The fact is that most electricity is produced by burning coal‚ and the use of nuclear power plants. Simply stated‚ the more electricity used‚

Bluethooth Wireless Technology Bluetooth wireless technology is an open‚ accepted standard for wireless communication. It was developed by Dr. Sven Mattisson and Dr. Jaap Haartsen at Ericsson Mobile Communications in Lund‚ Sweden. Initially Bluetooth was to be used as an interface between mobile phones and their accessories. It soon became clear that the uses for this new wireless technology were manifold and Ericsson decided to share their technology‚ offer free licenses to any company that

Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly

Physiological psychology is a complex but fascinating field of study. It explores the relationship between our biological systems and behavior. Structure and function of the nervous system from the neuron to the brain‚ as well as the interrelationships between the brain and such behaviors as eating‚ sleeping‚ learning‚ memory‚ emotion‚ and mental disorders will be discussed using examples from the behavior of both humans and lower organisms.
