The electronic power meter sensor module was developed as a part of a global intelligent management system for domestic power consumption management (TELEC) 1 for energy optimisation, both in terms of client costs and energy saving. Abs ract tThere is an increasing concern for the intelligent management of domestic power consumption based on intelligent sensors and actuators (attached to domestic appliances). This paper describes the electronic power meter sensor module of an intelligent management system being developed which is based on a network of functionally independent intelligent sensor and actuator modules. The actuator architecture has different modules to interface and read values from sensors and to communicate with other actuators.The management process is based in data acquired by intelligent sensors and actuators and controls home appliances based on environmental conditions and energy profiles, as well as several factors related to the comfort, commodity and security of users.The main project strategy was the development of a generic system composed of independent functional units (sensor and actuator modules) that can operate in a distributed control mode or under central controller supervision. This configuration gives the user a larger set of control options, as the control of a single appliance, a single space or division or the whole house.The electronic power meter sensor module is responsible for measuring energy and instantaneous and average power. Its functionalities allow it to be used for simple domestic electric power measurement applications. Moreover, it can store power consumption profiles and automatically identify and detect malfunctions of home appliance connected to the network at a given moment. The communication with external devices is implemented using standard serial interfaces.The block diagram of an actuator is illustrated in Fig. 1.
