Abstract

Sockets are electrical equipment that has been used to connect and disconnect electricity from a power source to electrical equipment. Rapid technological developments encourage people to create a reliable and easy-to-operate socket. So far, the operation of the socket is done manually by pressing the socket. The very rapid development of technology has encouraged people to create electrical plugs with greater capabilities and ease of use. Therefore, designed an electrical plug that can be controlled by an android smartphone. For operation through the android application, sensors are needed that can be used to detect all the parameters needed in the use of sockets, there are several sensors used, namely current sensors, voltage sensors, and bluetooth. This sensor is connected to the Arduino UNO. By using the android application, we no longer need to walk to the location of the socket, simply by giving an order via android then the task of the socket can be carried out.

Abstract

The development of the world of transportation, especially land transportation such as cars as well as the development of shopping centers, restaurants, entertainment and recreation facilities that are growing very rapidly make every entrepreneur who manages parakeet lands to think about parking spaces for future visitors. Customers will feel comfortable and calm if they are easy to find a parking space for their vehicle and easy to find their vehicle again. With this condition, it is necessary to have a tool that can tell customers where the empty parking blocks are so that customers no longer need to circle around just looking for empty parking blocks. The more crowded visitors who come to the parking area, the more busy the parking attendants who manage parking are Manually. Therefore, we need a way to solve this problem. Based on these problems, this research designed a vehicle parking automation based on the AT89S51 microcontroller where the microcontroller will check the condition of the parking entrance, if there is a vehicle in front of the door, the microcontroller will check the conditions in each place. If there is an empty place, the LCD will display the place, then the microcontroller will order to open the parking door. The door will close again after the vehicle enters. This process will continue until all parking spaces are filled.
