Design and development of desktop tensile test machine control system based on internet of things (IoT)

The tensile testing equipment plays a vital role in assessing a material's strength under an applied tensile force. Several tensile testing instruments incorporate electronic components like sensors, actuators, and microcontrollers to ensure data accuracy. Nonetheless, the integration of Internet of Things (IoT) technology for real-time control, data processing, and remote monitoring of tensile tests remains underutilized. IoT can revolutionize the testing process by enabling real-time testing via the internet. This research adopts an experimental approach that involves designing a control system along with desktop and web-based applications to govern, process, and remotely monitor tensile testing data. Calibration of the load cell sensor and specimen length changes is performed to assess the equipment's accuracy and precision. Functional testing of both the equipment and the developed applications is also conducted. The research successfully culminates in the creation of an IoT-based laboratory-scale tensile testing system, accompanied by desktop and web applications for real-time remote control and monitoring. The functional tests confirm the alignment of results with the equipment's design, with no deviations from expected outcomes during testing scenarios.
