The fourth industrial revolution has transformed manufacturing through cyber-physical technology. This system would allow for enhanced communication and quality in manufacturing environments. A key component of Industry 4.0 is the Internet of Things, which integrates sensors and software with networking capabilities. Despite its effectiveness, many manufacturing devices lack IoT capabilities. This paper proposes a low cost IoT system using a Raspberry Pi to read, analyze, and process sensor data with custom code. Visual programming software is used to display both sensor data and manually entered data, requiring operator judgment. The system's architecture and user interface are presented, demonstrating its potential in manufacturing environments. Potential expansions and further applications are also discussed, highlighting opportunities for innovation and improvement.
