This paper presents design and construction of AC modern meter. The meter is designed to overcome the error occur due to manual readings and minimize the space consumption of the unit. The meter is portable and adaptable as it can measure voltage, current, frequency, power, energy, power factor in a unit. AC modern meter have several advantages that includes measurement of residential electrical consumption, factory electrical consumption, laboratory measurement of voltage, current, power, energy, power factor and frequency. Individual meters are required to estimate electrical parameters, but the AC modern meter is abundant to measure voltage, current, power, energy, power factor, frequency and to display them simultaneously on an LCD. The designed AC modern meter computes the electrical parameter using an Arduino-UNO and PZEM-004T and display the numerical value on a digital programmed screen simultaneously. AC modern meter gives the accurate and efficient reading for electrical equipment and is also used for safety purpose while is in electrical circuit development and in testing lab. Multi-meter can measure voltage, current, frequency, but it cannot display all of these simultaneously, but whereas the AC modern meter is of great benefit in measuring and monitoring the voltage, current, power, energy, power factor and frequency.
