In this paper we will discuss about the working remote controllable room architecture which is possible by reducing standing power which in turn reduces the energy consumption. The power controller is designed by using embedded systems with microcontroller functionality. By using this we can efficiently manage the power outlets. By using various sensors we can detect the usage and based on that the load elements get on. We use a controller which automatically reduces the standby power when there are variations in power flow.
Room architecture and microcontroller working:
We find light sensors, temperature and humidity sensors which sense the information of the room and pass it to the microcontroller. To the microcontroller we connect different appliances through a relay. Based on the sensed information given by the sensors the microcontroller makes the appliances to turn on or off. To drive the relays we will use an pre ULN 2003 drive which gives the required motion for the relay.
We use a pic16F877A microcontroller which has additional features which is suited for our design requirement. It has a 16 bit timer and 10 bit ADC and 256 bytes of EEPROM memory and it executes the code at the speed of 1microsecond which is faster than a microcontroller execution. We can code the microcontroller using c language and the program is loaded into the microcontroller using PIC flash.
The proposed model can be implemented to a single room. By using this model we can reduce the usage of power flowing to the appliances and this model is available at a low cost. We can design this model by using wireless communication through Zigbee protocol and we can interconnect rooms through servers. Thus we can conclude that the proposed model works efficiently in saving power in room architecture.
