Abstract

The development of Internet of Things (IoT) technology has made a significant contribution to internet-based monitoring and automation systems. In vocational education, particularly in the Mechatronics Study Program, the implementation of IoT technology is crucial to support practical activities and improve student competency in embedded systems and data communications. This research aims to design and implement an IoT-based temperature monitoring system using a DS18B20 sensor, an ESP32 microcontroller, and a local I2C LCD display. The developed system is capable of measuring temperature in real time and displaying data both on the LCD screen and via an IoT network. The research methodology included hardware design, software development, system integration, and sensor performance testing against a digital thermometer as a reference measuring instrument. Test results showed that the DS18B20 sensor has a fairly good level of accuracy with a small relative error compared to the reference measurement. This system implementation has proven to be an effective practical tool for IoT learning in the Mechatronics Laboratory. The developed system is modular, allowing for further development with the addition of other sensors and cloud platform integration
