Abstract
Technique has been proposed to modernize the existing billing procedure. In this
project, 8051 microcontroller have been used to control the main operation which is
being performed in this system. Electromechanical meter has been installed in this
project to measure the consumption of power in kilo – watt hours. To get benefits of
GSM techniques a GSM module has been implemented in this system. Module has been
interfaced with microcontroller, and microcontroller communicates with module
through AT Command. External memory has been interfaced with microcontroller to
store the units which will be charged by suppliers. Opto coupler sensor which is hybrid
of photo diode and infrared light emitting diode, have been used to detect the motion
of metallic which continues its motion to show the consumption of power. This sensor
has also been interfaced with microcontroller to receive the pulse on the completion on
one revolution of a disc. Triac has been used to work as a switch it also receive signal from microcontroller to control the switching of power supply. In this way both
suppliers and consumers get benefits of this technique.
