Th e objective of this project is to develop a novel multifu nction meter that can allow consumer to monitor load usage (at rem ote place) and also provide consumer to select optimum load scheduling, load shedding and load monitoring. In this project a multifun ction meter has been developed which can sense both voltage and current by means of voltage sen sor LV20 - P and current sensor LA 25 - P, the output of the vol tage and current sensor are interfaced to mbed Microcontroller LPC1768 which is the main control unit in this project . The LPC1768 mbed Microcontroller will continuously monitor load voltage and current by means of voltage and current sensors and also calculate all basic electrical parameters like Vrms, Irms, Vavg, Iavg, V(t), I(t), Vm, Im, FFv, FFi, P, Q, S, PF etc. in each and every instant. A ll these parameter are monitor on Display HD44780 and also all these electrical parameters are sen d to mobile phone by wireless Bluetooth technology LM400. The multifunction meter is simulated using Matlab Simulink and also a laboratory prototype also has been developed and verified at varying lamp load condition. At different lamp load condition all a b ove basic parameters observed on display, mobile phone and laptop .
