Recent days in this world the population growth is rapidly increasing, so the world has number of aged people. These aged people are living lonely in home or old people home or retirement home and so on. The aged person have many diseases like memory loss, fits and etc., so that they cannot live independently in their home, if they need long life and precious independence they must stay in monitored environment. In this paper, we present the design and development of welfare facility for elders system which is based on wireless sensor network. Here we use sensors for monitoring aged people. If the sensor detecting any abnormality pattern in aged people, the system customary activity will automatically generate and send the text message or E-mail or both to the care giver and family members. Here we use Hidden Markov Model [HMM] for reducing data transmission time to care giver and family members. Also we design the database security which would provide more security to database in controller system. Here we use message digest algorithm [MD5] for providing security to database in controller side. Also display the monitoring status in web page that could take appropriate action by the person who notices it.
