Smart Laboratory Using Radio Frequency Identification (RFID) Based on The Internet of Things

Abstract

In Indonesia, traditional methods are still commonly used for managing laboratories. This has resulted in various issues, such as the loss of keys, and has hindered the efficiency of these laboratories. However, the integration of technology has the potential to improve laboratory management by up to 33%. A modernized laboratory system, known as an "Innovative Laboratory", combines technology with traditional management techniques. The proposed Internet of Things-based tool aims to assist laboratories in improving their management services, including a registration system, a locker system, and a desk system. This tool utilizes a Keypad 4x4 and PCF8574 to select desks and lockers, Node MCU as a microcontroller to publish identification data from an MQTT broker, and RFID technology to access and activate electronic locks and sockets. To ensure that data is successfully transferred and the selected locker and desk are available, the system requires a certain delivery time for a maximum of 251 bytes of data that can be sent at different signal strengths. Only registered users with valid identification are able to access the locker and desk systems, and users must unregister before switching to a new locker or desk. The goal of this system is to streamline and improve the management of laboratories.

IoT APIs: Time Response Optimization in Edge Computing Data Communication for Power Phase Detection System

“…The constraint of utilizing APIs is the long response time, making it impossible to obtain data in real time [13,15]. Long response time will not be a problem in systems that do not need real time, such as IoT-based systems for monitoring livestock conditions [16][17][18] and locker accupation in smart laboratories [19]. But for early landslide detection systems [20], mitigation systems for fire emergency response [21], and detecting phase sequence detection in 3-phase electrical systems with a frequency of 50-60Hz which need to compare wave data from the power source side with the load side, requiring data in real time.…”
