A n example of pervasive computing is the replacement of power meters from electric types to smart meters. Smart meters sends usage data over the Internet to the managing company. The older electric meters, on the other hand, required a physical visit from a representative who collects data.
The core of pervasive computing technology is the development of the Internet, advanced electronics and wireless technologies. Products created using this technology typically allow for real-time data collection. In the case of the smart meters, for instance, both data regarding usage and power outages can be communicated to the monitoring electric company.
