"description": "<p>This paper is formed by keeping the power consumed in the malls. As the shopping malls are the global phenomenon where every little outdoor bazaar products are sold. People not only find malls for purchasing goods, it is also known as a cultural hot spot where people of all ages meet up to interact. As everyone of us know malls consume a lot of energy and not all energy are used in an efficient manner. So, to overcome this energy loss, PLC&rsquo;s are used to automate the malls. To start with, the parking system is fully automated so that only a specific number of vehicles can be parked inside. The door of the parking will be opened and closed automatically until the parking is full. When the parking is full the buzzer will beep so that the further incoming vehicles will be directed to another parking area thereby avoiding confusions. Elevator will be present to take customer from basement parking. Once the customer reaches near the elevator the elevator will be directed to basement. Another small way to reduce power wastage is that if elevator is present in two different floors then the elevator will move to the floor which is nearer to the present floor. This process is done by comparing the distance between the present floor and the floor which the elevator is to be moved. The elevator will move to the floor which has less distance from the present floor and therefore a little amount of power and the customer waiting time can be saved. &ldquo;Saving each penny will help you to build a house one day&rdquo;. Air-Conditioner of the malls are also adjustable according to the temperature. The temperature is constantly being monitored by a Resistance Temperature Detectors (RTD). If there are a lot of people then it would naturally be warm so that the temperature of the Air-conditioner is further reduced so that more cooling takes place and automatically as more people leave out the mall would be cool if the same temperature is maintained, therefore the temperature is raised accordingly. Lights and Airconditioner get turned off when there is no one in the mall. For further development PLC&rsquo;s can be used for theft protection in each shop in the malls. If there is no one inside the shop then all the power coming to the shop will be cut off and then if there is someone who breaks the door or the window then a buzzer is made to make noise</p>",
