In this work, a wireless energy consumption monitor made up of a current transformer with its analog interface and an 8-bit microcontroller that acquire sensor's data is presented. The whole system is wireless connected to a PC through a Bluetooth module for the sending of the data that are managed and collected by the host software developed in Lab VIEW, a multiplatform graphical programming environment. A digital programmable potentiometer have been used to allow the system's electronic to dynamically tune the sensitivity of the measurement by means of the firmware implemented in the μC that let to obtain both result accuracy and a fast convergence of the algorithm. The entire design address the need of the reduction of the electronic system's energy consumption with the utilization of advanced low power technique both hardware and software.
