density based traffic light control system using microcontroller 8051 pdf

The project is designed to develop a density based dynamic traffic signal system. The signal timing changes automatically on sensing the traffic density at the junction. Traffic congestion is a severe problem in many major cities across the world and it has become a nightmare for the commuters in these cities.

Conventional traffic light system is based on fixed time concept allotted to each side of the junction which cannot be varied as per varying traffic density. Junc ....etc

The 8051 Primer board is specifically designed to help students to master the required skills in the area of embedded systems. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The kit supports in system programming (ISP) which is done through serial port.

NXP s 8051 (89V51RD2), 8051 Primer Kit is proposed to smooth the progress of developing and debugging of various designs encompassing of High speed 8-bit Microcontrollers.

Traffic light system was one of the fascinating applications of Embedded systems and have been using the same till this day. I have previously posted a simple Traffic light system for one way roads with small timings check it out if you are interested in it. This is the four way traffic light system using embedded systems which was bit complex in nature as we need to consider the traffic flow in four different directions providing appropriate timings to each of the lights.

This system uses 8051 microcontroller ( AT89C52) , 7-segments and LED ....etc

A three digit contact less digital tachometer using 8051 microcontroller which can be used for measuring the revolutions/second of a rotating wheel, disc, shaft or anything like that is introduced in this project. The tachometer can measure up to a maximum of 255 rev/sec at an accuracy of 1 rev/sec. What you just need to do is to align the sensor close to the reflective strip (aluminium foil, white paper or some thing like that) glued on the rotating surface and the meter shows the rev/sec on the display. ....etc

heart rate monitoring system using at89s52 source code by using keil microvision

In this module we used advanced technology for patient monitoring those who are suffered from heart diseases & physical disorder. Therefore heart rate sensor and temperature sensor are used for patient monitoring. Sensors gives accurate output therefore it rules out the use of traditional medical instruments such as thermometer and other devices. For continuously sending message from patient s location to medical advisory GSM modem used. This module provides reli ....etc

Irrigation is defined as artificial application of water to land or soil. Irrigation process can be used for the cultivation of agricultural crops during the span of inadequate rainfall and for maintaining landscapes. An automatic irrigation system does the operation of a system without requiring manual involvement of persons. Every irrigation system such as drip, sprinkler and surface gets automated with the help of electronic appliances and detectors such as computer, timers, sensors and other mechanical devices.An automatic irrigation system ....etc

SUMMARY:
Embedded systems to quickly achieve widespread, blurring the line between science fiction and reality. These systems are found in almost every electronic device in use today. In fact embedded systems is not new technology, but it came into focus only recently, thanks to the convergence of many technologies such as telecommunications, consumer electronics, automobiles (MPFI), factory automation, smart cards, motion control using a huge mo Mikroprocessor. Embedded systems into our lives in such a radical way that most of us might not ev ....etc
