Design a Temporary Package Storage System Using Arduino Mega 2560-Based Password

Online shopping is an activity that is carried out between buyers and sellers online and then sent using courier services. So, at the time of delivery, the package requires a clear address, correct and the delivery time can already be estimated. A courier can complete the delivery of the package perfectly if the buyer/booker receives the package in place directly. The problem is that if the buyer /booker does not receive the package, then the courier will delay the delivery until the package is received. This paper aims to build a secure, privacy and confidential package storage system consisting of a keypad for password input, a servo motor for opening and closing doors, ultrasonic sensors for detecting incoming goods, SIMSOOL V2 for SMS message notification, and Arduino Mega 2560 as the main control of the system. Based on the results of tests and analysis that have been done, the keypad has a delay of 100 seconds in filling in every 1 digit of the input password. Setting the minimum limit value as far as 10 cm, then get the visibility of the HC-SR04 sensor that can be read as far as 10 cm to 12 cm. Package materials coated with iron, plastic, wood, paper, glass, and fabric are capable of detection by hc-SR04 proximity sensors.
