ALAT PENGUKUR PEMAKAIAN ENERGI LISTRIK MENGGUNAKAN SENSOR OPTOCOUPLER DAN MIKROKONTROLER AT89S52
Abstract: kWh-meter as an each
hour electrical energy consumption measurer is still using conventional tools
which only records the amount of electrical energy used in each hour. By using
AT89S52 microcontroller and optocoupler sensor, the conventional kWh-meter was
modified to be a measurer which is not only display s the amount of the used
electrical energy but also shows the value of money in rupiahs that should be
paid by the customer. The principle of how this system works is PLN as a power
source of kWh-meter moves the disc of kWh-meter when it is in the underload
condition. When the disc spin and pass the optocoupler sensor, the sensor will
turn on. Each time the disc cuts the beam of light, the sensor will instruct
the microcontroller, the main controller, to process the execution instruction.
This execution instruction results in the reading of both a number of rounds
per kWh and an amount of rupiahs display ed in LCD.
