Now the pulses produced at the pin CF is directly applied to the counter pin of the microcontroller. The microcontroller counts the pulses that appear at pin 1 of Microcontroller (ATmega32) within every 20 seconds. The number of pulses per second appeared at pin
22 of Energy Meter IC is directly proportional to the instantaneous real power information for a particular load. Information such as power, energy, and maximum demand are stored at the EEPROM of the Microcontroller (ATmega32).
