A simple system for telemonitoring the daily life of an aged person living alone.
A simple system for telemonitoring the daily life of an aged person living alone was developed. The system consists of a current sensor and a pair of computers. The sensor detects changes in the power line current of electrical appliances. The computer at the aged person's end transfers the output signal of the sensor every minute to the computer at the family end via the Internet. In this preliminary study, three days trial was conducted, and changes in the output signal of the sensor were monitored without any trouble. If this system is used, a family may be able to estimate a parent's living condition inexpensively and in real time.
