Development of a Real‐Time Monitoring Sensor Box for the Purpose of Chemistry Lab Usage

This study presents a sensor box designed to conduct scientific research and to motivate other young students in a chemistry university environment to learn about sensors and their usefulness. The main focus of this study is on the usability and designs of this particular sensor box that we developed using accessible components: a Raspberry Pi 5, an Arduino Uno, and DFRobot's Pro sensors for temperature, conductivity and pH measurements along with developing the necessary software to conduct these measurements in the most convenient way, which includes creating a GUI, a data saving script, and automating the measurement process. To test the functionality of this sensor box, we utilized it to monitor hydroxyapatite (HAP) formation reaction to observe the changes in conductivity and pH throughout the process.
