The board has only one  relay driven by TTL circuit . The board works on 5V but the input signal can come directly from Raspberry Pi and Arduino  output working at 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

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.

In recent years, it has become a fantasy that the people put their lives in risk. More often, the people consume alcoholic drinks and drive the vehicles. There are more chances that the person can hit the vehicle to any obstacle approaching him in the opposite direction due to unconsciousness caused by drinking. Hence, we make a modest attempt to design and develop a simple, low cost alcohol detection android application using an independent microcontroller.

What if light could beside just illuminate, also send streams of data? all of a sudden daily lighting, like traffic light, television sets, headlight and other lamps ,become far more important .we could have streetlights sensing maps to navigation systems for example or create an ad hoc network using office light.

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.
