Abstract

The Internet of Things (IoT) is a network of interconnected devices that enables these objects to collect and exchange data. IoT offers an efficient solution for various fields, including the database recording of borrowing and returning calibration standard measuring instruments. This research aims to design and implement an automated IoT-based borrowing and returning system to support database recording effectiveness. The focus of this research includes the design of the borrowing and returning system, the method of transmitting data to Google Sheets, and email notifications when borrowing or returning activities occur. The research methods include the design of hardware consisting of a fingerprint sensor, infrared sensor, ESP32 microcontroller, liquid crystal display (LCD), and 4x4 keypad, as well as database recording to Google Sheets utilizing Google Sheets scripts and email notifications via Simple Mail Transfer Protocol (SMTP) connection. The research results show that the system was successfully developed with a high success rate for personnel identification accuracy, reaching up to 92%, with an average identification time of 1.42 seconds. Additionally, the developed system proved to be an effective solution for replacing the manual borrowing system, based on a survey of laboratory personnel.

Abstract

The development of e-commerce services requires a solution to facilitate the delivery of packages from couriers to users while maintaining package security. This research aims to design an automatic package receiving box using an ESP32 microcontroller as the control unit. The research method uses a prototyping approach through the stages of problem identification, prototype design, implementation, and function testing. The system is equipped with a GM66 sensor to scan barcodes as package validation, a load cell sensor to detect the presence of packages, and a Telegram application as a communication medium with users. The design process includes hardware and software requirements analysis, schematic creation, and draft design. When the system operates, the barcode is scanned by the courier and verified with the receipt number stored in the database, and the locker door will open automatically if the data matches. The test results show that the system functions properly, the GM66 sensor can read the barcode accurately so that the door lock solenoid can open the locker, and the message on the LCD can be read by the courier. This system shows potential in improving security and efficiency of delivery in e-commerce services.
