The Aim Of This Project Was To Work On Room Occupancy And To Provide Solutions And Ideas On Find Out How To Detect If A Room Is Occupied Or Not Using Generic And Non Costly Sensors. That Is Motivated
The aim of this project was to work on room occupancy and to provide solutions and ideas on find out how to detect if a room is occupied or not using generic and non costly sensors. That is motivated by the fact that buildings account for 50% of the overall power consumption in the US and 30% of it`s wasted mainly because of a foul administration of mild, heating, cooling and ventilation techniques. With the ability to know if rooms are occupied or not would then enable us to automatize these methods and make them more energy efficient. The sensors studied in the method were a CO2, relative humidity and https://www.kharkhorincourt.gov.mn/user/trunkgolf05/ temperature sensor, a digital camera, a WiFi sniffer and a PIR(Passive infrared) sensor. All of them were implemented and tested to see how they might measure occupancy. After analyzing each sensor alone we had to mix them to acquire the best possible accuracy. To take action, two methods have been tried.
