Abstract

Development of Social Distancing Departmental Store Trolley (SODIT) using Arduino is a device that was built to help in fighting Pandemic Covid-19. Pandemic Covid-19 have changed our life style accordingly to meet the standard operating procedure for avoiding virus spread. The hardware and software components of this project are distinct. This division was formed for the purpose of assisting with the overall design and development of the system in this project. The trolley's design and circuit modelling are the two primary components of development. To construct the application system, this project uses the Arduino UNO as the main controller. Ultrasonic Sensor for determining consumer social distance and Passive Infrared (PIR) Sensor for determining object motion by detecting their temperature were the two key components of the project. By combining these hardware and software key element will lead to Development of Social Distancing Departmental Store Trolley (SODIT). If PIR sensor detect a person it will triggered high and will go to Ultrasonic sensor to check condition either the distance is less than 100cm or not, if less than 100cm the sensor will trigger the output. These two conditions for each sensor must be met each other in order to produce the output, either one is not met, the output signal cannot be produced. For output require a simple electronics device such as LED or Buzzer to warn or alarm the user. In order to reduce power consumption used by this trolley, a 5V DC power supply (powerbank) will be used to generated the trolley. This because, the development of this SODIT Trolley does not required a complex and high used of power in this system such as servo motor, automatic breaking system and so on. All this features will effected the power consumption of this departmental trolley. By this implementation, in this pandemic situation the development of Social Distancing Departmental Store Trolley (SODIT) will be develop with technological developments.
