Role Of Digital Ic Msp430 In Electricity Measuring Unit

No comments
Electronics is an area within the science which deals with concepts such as effects of electrons flowing through the circuits , role of signals (continuous and binary) on the unit/system . Implementation of electronic devices almost in all the areas of human activities has contributed towards the successful rise in complex devices, micro-electronic components as well as complex technologies and technical problems too . This article had just tried to explain the importance of a small particular electronic device (MSP430 Integrated Chip) which is just a few mm in size . 

 Meter or an energy meter is a device that measures the amount of electric energy consumed by residence , industries or electrical power devices . Why MSP430AFE2XX ???????? . It has got 16 bit RISC architecture , 125 nsec per instruction , 3 independent ADCs , low power supply voltage range 1.8V to 3.6V, wake up time from sleep mode is < 1 microsecond ,FLASH (16KB) & RAM (512B) , system frequency 12MHz and most importantly its “ANALOG FRONT END (AFE)” feature . AFE is a set of analog signal conditioning circuit that includes amplifiers , filters & sometimes includes application specific integrated circuits that are needed to interface variety of sensors to ADCs . Software is implemented to perform 2 processes . Background process : it uses a program for triggering the ADC . ADC will collect voltage and current information/data. This data gets stored in a buffer .Foreground process : This accumulated data is then used to calculate VRMS, IRMS, power & frequency which is then displayed .

Goal of this article is to make readers know that how electronic field play a vital role in our day to day household life .
