Digital Multimeter (DMM)



INTRODUCTION:

The cathode-ray oscilloscope (CRO) is a common laboratory instrument that
provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies. Its
reliability, stability, and ease of operation make it suitable as a general purpose laboratory instrument. The
heart of the CRO is a cathode-ray tube shown schematically in
The cathode ray is a beam of electrons which are emitted by the heated cathode (negat ....etc

ppt on conversion on sound into electrical energy

Abstract

In this work, a relatively less explored source of green energy is proposed. Random sound energy around us can be treated as a source of electric power after their efficient conversion using suitable transducer. An effective way of producing usable electric power from available random sound energy is presented here. Piezoelectric transducers are used for conversion of sounds into electric energy. The produced electric energy from multiple piezoelectric transducers are stored in multip ....etc

code for celsius and fahrenheit scale digital thermometer using 8051 microcontroller at89c51

description:
A digital thermometer can be easily made by interfacing a temperature sensor to the microcontroller AT89C51. The temperature sensor used in the project is LM35. The LM 35 IC generates a 10mV variation to its output voltage for every degree Celsius change in temperature. The Output of the temperature sensor is analog in nature so we need an analog to digital convertor for converting the analog input to its equivalent binary output. The ADC ....etc
