Design IoT Based Smart Electricity Power Saving University: Analysis from a Lecture Hall

Managing and controlling the electricity consumption in a productive manner is a red hot topic in today’s world. Many countries have considered this problem and they have suggested automate systems to overcome this problem. Since, Sri Lankan has not used such kind of automated system to control the electricity power consumption, our system will be a suitable solution for that. Today, IoT is a technological paradigm that is used to build such kind of automates systems. In our proposed system also, IoT and sensor technologies are used. It is a system that responds to human presence and provides related actions according to the human occurrences area environmental condition. It is control the electric devices such as lights, fans and AC in the lecture hall according to temperature and light intensity values that detect by the sensors.  We used Kinect sensor to detect human presence. DHT22 and LDR sensors were used respectively to sensor the temperature, humidity and light intensity of human occupant area. Arduino- mega board was used to control the DHT22 and LDR sensors. In the research process we found the comfortable temperature and light intensity values that suitable for lecture hall and used those values to implement the prototype. Also, it provides real-time information such as current environmental condition of specific place and relevant messages including actions that need to take by using website. The main objectives of this research are reduce the wastage of electric power and provide suitable IoT based solution for reduced the electric power consumption.
