SMART OFFICE AUTOMATION FOR ENERG SAVING USING IoT

Abstract

Due to day-by-day increase in the cost of energy, it has become a need of every individual to efficiently consume energy. This project presents a detailed description of how to save and better utilize energy and make tasks easier by using Internet of things (IoT). All the office appliances are automated to avoid waste of power due to human behavior. If a person is not present in a room, all appliances such as fan, air conditioner and heater should be turned off to save energy. In this thesis, if a person enters in a room, the lights turns on automatically by use of IoT paradigm. In the presence of a person in a room, the air conditioner or heater must be managed automatically. The light and exhaust fan of washroom is turned on automatically when a person is using the facility, and light is immediately switched off when not in use. The exhaust fan of the washroom remains on for two minutes after the person exits and then it turns off automatically. In order to keep the record of all the power consumption at a facility, a current sensor is used that measures current consumption and a log is created in the database. The user can access the usage statistics through a web application. In order to keep user aware of the presence of harmful gases or smoke in case of a fire, a toxic gas sensor is also used that is connected to an alarm. The users are notified and are kept aware, through a web application, while the logs from sensor data are created in a database. A web application is also used to control appliances by analyzing data from different type of sensors while keeping in view the user settings.
