Abstract: In the jewellery casting industry, the accuracy of electrical parameters such as voltage, current, and temperature is crucial for ensuring quality and safety. Traditional monitoring methods often involve manual inspection, which can lead to errors and inefficiencies. This paper presents an innovative solution for real-time remote monitoring of jewellery casting machines using a combination of Human-Machine Interface (HMI) and IoT-based technologies. The system collects data from various sensors (current, voltage, AC, DC) interfaced with Atmega microcontrollers and transmits it through an ESP32 module to an AWS-based backend. Data is stored in MongoDB and is accessible via a mobile application developed in React Native, allowing operators to monitor the casting process remotely. Additionally, this work explores the use of CAN and RS485 communica- tion protocols to ensure reliable data transmission between the system?s components, particularly between microcontrollers (like ESP32, TMS320F280049C and DSPIC33ck256MC506). The novelty of this system lies in its dual-protocol architecture (CAN + RS485) with seamless HMI and mobile integration over AWS, specifically tailored for real-time remote monitoring of jewellery casting machines?a domain currently underserved by industrial automation literature.
