Microcontroller Based Dielectric Constant Measurement

A dielectric constant measurement setup has been developed to measure dielectric constant of liquids using AT89C55WD microcontroller. A modified operational amplifier based AC Schering Bridge network is used to compute capacitance and hence calculate dielectric constant of liquids. This instrument system permits recording of dielectric constant of liquids at various concentrations and temperatu...

Low Cost Microcontroller Based Decay Measurement System for Display Phosphors

An attempt is made to design and develop a low cost, simple but efficient instrument to measure the decay time of luminescence in phosphors used in displays. The approach employed here is generally an embedded system designed around an intelligent microcontroller Atmega-16 of Atmale. The system is using a time domain technique of measurement and is further enhanced by developing necessary softw...

Microcontroller based parameter monitoring system

The purpose of this paper is to acquire the remote electrical parameters like Voltage, Current and Apparent Power and send these real time values over GSM network using GSM Modem. This facilitates the remote monitoring of these parameters without any geographical constraints, since a GSM module is used. Real time power monitoring system relate generally to the field of electric energy consumpti...
