Android mobile phone application developed in order to extended data communication range of our wireless health monitoring device..

Patient monitoring systems are gaining their importance as the fast-growing global elderly population increases demands for caretaking. These systems use wireless technologies to transmit vital signs for medical evaluation. The aim of the project is to provide a better health care to people from house in more economic and pertinent friendly manner. The need of home based health monitoring system is increased now days because health care cost is increasing exponentially in last few decades. In the proposed home based health monitoring system using android smart phone includes the aspects of acquisition of medical parameters like Body temperature and Pulse rate.

Automatic Meter Reading DIY Kit- UNO ATMEGA328

Automatic meter reading, or AMR, is the technology of automatically collecting consumption, diagnostic, and status data from energy metering devices (electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. 

Power line communication refers to the concept of the transmitting information using the main

power line as communication channel. The Greatest benefit of the power line communication systems is that they use existing power lines as communication medium instead of using costly wireless equipment or dedicated communication wiring and hardware. This provides a strong motivation to use an existing power lines for communication purposes in addition to their use for power distribution thereby, taking advantage of already existing electrical network that is present in almost any building, whether industrial,commercial or residential.

The main aim of this project is to develop a system, which usesMobiletechnology that keeps monitoring of the various appliances, and will control the operation of these appliances with respect to the signal sent by the mobile.

LCD stands for Liquid Crystal Dispaly. It can be used to display anything. They are of many types. The ones we commonly use for embedded systems, robotics, etc are of two types – character LCD and graphical LCD. The 16x2 LCD Characters have their own limitations; they can only display characters of certain dimensions. The Graphical LCDs are thus used to display customized characters and images. The Graphical LCDs find use in many applications; they are used in video games, mobile phones, lifts etc. as display units.
