SISTEM PENCATATAN KWH METER BERBASIS MIKROKONTOLER AT89C2051 MENGGUNAKAN PORT SERIAL

Record-keeping of analogue KWH metre result to the number of happened

mistake in its applying. Digital KWH metre required to reduce mistakes of recordkeeping

of electrics usage, both of technical mistakes or non-technical mistakes

(such as human error). To apply this digital KWH metre required time and

expense. In order to fulfill the needs as well as avoid the using of digital KWH

metre, a system wich have ability to enhanced at analogue KWH metre required

to alter analogous data become digitally.

This matter can be realized by making a microcontroller-based system

wich able to process analogous data become digitally. The system can be selfsupporting

by exploiting electric power emiting a stream of the KWH metre.

System will save data at the memory, so that will avoid losing of data when system

losing of energy.

This system is provided with serial communications port wich able to be

connected at computer in order of configurate the system. Software for this system

is also made to water down configuration.
