Abstract
A review of wireless sensors and sensor networks, especially for in-home monitoring of elderly people, has been presented in this paper. The characteristics of various sensors for monitoring applications have been studied. The requirements of the sensor for making a smart sensor network have been investigated. A typical in-house developed system for home monitoring and elder-care application has been presented. A few patents on the sensors for home monitoring have been reviewed.
Keywords: current sensing, non-intrusive monitoring system, radio frequency communication, Wireless sensor network, hardware interfacing, elderly care
