Networked switching and polymorphing control of electrical loads with web and wireless sensor network

All the electrical load cannot be controlled using occupancy sensors in buildings/home especially in large public building, this results need for manual control on supervisory manner due to importance of the load or the service requirement. This requires switch box to be fixed on wall/nearby close to the load. To operate the same the person has to travel to the switch box. As the technology keeps growing to serve the mankind the expectation keeps on increasing There is no limit for sophistication. This paper intended to demonstrate web based control for Electrical loads in combination with the wireless sensor network based switch box which provides local mobility to control the load and also the same function can be done through internet. We introduce the wireless sensor network based mobile switch box for sophistication along with embedded web server based control the user can use the wsn switch box or internet to control the electrical load. The load status can be monitored in the web page. We also introduce the concept called polymorphing control by which one mobile switch box designed for one location can be used to control the electrical load in other location. We use open standard embedded controller Arduino mega with Ethernet and xbee nodes. The switch box operates at 3V which more safe and saves the wiring cost partially. Also the power to room completely cut off when the loads were in off condition by fixing the controller outside the room which increases the fire safety. This flexible operation brings energy efficiency.
