battery level indicator project using 8051 microcontroller

Here is a easy to build low battery level indicator circuit that produces a visible indication by flashing a LED when the battery voltage drops below a predetermined voltage.The circuit is based on Panasonic s IC MN13811G and a efficient flasher based on transistors Q1&Q2.Here when the battery voltage drops below 2.4 V the output of the IC is activated and the flasher starts flashing.This circuit here is an ideal one for monitoring the level of all types of 3V batteries.The circuit ....etc

DATA LOGGING SYSTEM



Introduction
In the field of engineering, probably the most important aspect is collection, analysis and storage of on-field data. This broadly can be classified as Data Logging . Data logging has seen a repertoire of changes with progressing technology. Initially, what started as measurements with standard devices like thermometers, hygrometers, barometers has now become ever more accurate, fast and reliable with dedicated sensors to measure virtually any ....etc

Data Acquisition and Data Logging



What is data acquisition and data logging
Data acquisition is simply the gathering of information about a system or process
Information may be gathered for various reasons
knowledge
research and development
systems or process monitoring
systems or process control
Data acquisition requires one or more transducers (sensors) to sense the system or process, and a signal measuring instrument

Data acquisition system project is a fine combination of analog and digital electronics. This project is designed so as to fulfill the requirements of the industry applications, home applications. The project consists of parameters monitoring, parameter storage. PC interface is one of the main features of the project in which various data like value of parameters, date and time are sent to the PC.

We have used Microcontroller as a main component of the project. Now a Microcontroller has become a main component of many of the electronic circu ....etc
