Wireless sensor network based home monitoring system for wellness determination of elderly

  1. 1. Wireless Sensor Network Based Home Monitoring System for Wellness Determination of Elderly Abstract Elderly people desire to lead an independent lifestyle, but at old age, people become prone to different accidents, so living alone has high risks and is recurrent. It is necessary to monitor the activities of the elderly or handicapped persons are alone when their care-takers are not in home. In the present work, an intelligent home monitoring system based on ZigBee wireless sensors network has been designed and developed to monitor and evaluate the wellbeing of the elderly living alone in a home environment. Wellness of elderly can be evaluated for forecasting unsafe situations during monitoring of regular activities. Existing System: In existing method the usage of household appliances is identified only by checking the running condition of a device. And there is no method to calculate the current and voltage values which is consumed by the electrical devices which are in use. Hence we go for new system. Proposed System: In this system, the usage status of the electrical devices in homes by the elderly persons is collected and transmitted in wireless mode to the monitoring section which consists of PC with internet. Thus the status received from the home section is viewed in PC and also updated in internet, by doing so their care-takers can view the status by logging into his home site. Thus they can monitor their elder persons and also know the status of device used by them at real time through internet. A LCD is there to display the current sensor values of electrical devices which are all used by the elder persons in home.
