Sensing the environment and the body of care recipients is the cornerstone of any e-care system. In this paper we present the home infrastructure modules necessary for this sensing. We then focus on the sensor groups offering specific context extraction capabilities, the processing of their signals, the description of the resulting metadata and their local storage. Utilising the extracted context description, the caring system is enabled to offer personalised services to the care recipients.
