contactless digital tachometer using 8051 abstract

Contactless digital tachometer using 8051.
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 rotatin ....etc

The liquid crystal display (LCD) is very commonly used electronic display module and have a wide range of applications such as calculators, laptops, mobile phones etc. 16 2 LCD character display is a very basic module that is used Commonly in electronic devices and projects. It can display 2 lines of 16 characters. Each character is displayed using 5 7 or 5 10 pixels matrix.Interfacing 16 2 LCD with 8051 using Keil C is a bit complex because there are no powerful libraries in Keil C. To solve this problem we have developed an LCD library Wh ....etc

keil code for automatic street light system

Automatic street light system is very common nowadays as it provides intelligent street lighting mechanism. It provides light automatically during night without any human interference. These energy saving street lights make use of incandescent lamps instead of LEDs.So here I will teach you how to make an electronic circuit for street light automation. The heart of this circuit is a LDR (Light Depended Resistor) which is connected as a potential divider with a 56K resistor. The drop across LDR is used ....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
