MS Thesis

    Infrared Learning Remote Control Attachment for Motion Sensor to Control Air-Conditioner
    (Thesis Advisor: Dr. Vishal Garg)

    Very often electrical loads such as lighting, HVAC (Heating, ventilating and air conditioning) devices are switched ON when space is unoccupied. This is where most of energy is wasted and a feasible way to overcome this is by detecting occupancy and switching OFF when ever space is unoccupied.Occupancy sensors are used for controlling various devices such as artificial lighting etc for sometime now. However, most of the occupancy sensors available today use an electromagnetic relay for switching between ON/OFF states. These are preferably used for low wattage devices such as lighting and fan but not for high wattage devices such as air-conditioning systems, which require high current rated relay.In this thesis, I proposed and developed a system “IR Learning Remote Attachment for Motion Sensor to Control Air-conditioner” which uses infrared remote control technology to control air-conditioner and HVAC systems.

Projects

  • Portable and Powerful MP3 player for Automotives

    • The conventional stereo cassette player and CD players uses mechanical parts to run cassette tapes and CDs which are damaged very often to vibrations and jerks in automotive field. A portable and powerful MP3 player based on semiconductor memory (FLASH) designed in view of automotive environment where it does not need any mechanical parts. In this design ROHM semiconductor host mp3 decoder has been used to decode mp3 files and play. The advanced 20+20 watt Class D amplifier has been used for amplification and to suit portability.

  • Monitoring of Distribution transformers (DTs) using cellular communication

    • Monitoring of DT using Cellular communication is meant for measuring, monitoring electric consumption at Distribution Transformer. This system provides the facility to measure the values at distribution transformer and monitor them at remotely located monitoring station. One user interface has been provided through which administrator can see the graph of all the parameters. Threshold has been defined to control each parameter at distribution transformer , so when any parameter value exceeds threshold it generates an alarm. This provides real time monitoring and immediately recovery action can be taken which will avoid damage.

  • Mobile Phone as Universal Remote Controller

    • The rapidly advancing technology and the reducing cost is increasing the usage of remote controlled devices in home automation systems. These devices use various media (such as IR, RF, and Wire) and protocols (such as BACnet, LonTalk and X10) for communication. Instead of using several remotes a composite universal remote with different communication protocols and medium would be desirable. Another alternative is a gateway which supports different protocols and media and connects to a simple remote. Mobile phone comes out to be a suitable candidate for the simple remote because of its widespread use, possibility of individual settings, display, buttons, and wireless communication. A prototype demonstration implemented at IT in building science that has a gateway centric mobile based home automation system. Gateway acts as a multiple protocol transceiver which receives the commands from mobile phone via Bluetooth and transmits the commands to different devices via different protocols and different media.
