Design of IoT device using beam-splitting prism display

This project is based on an open-source hardware. Its functions have been redesigned and improved, with enhancements made to the hardware programming and power supply circuits. System-level secondary development has been carried out to implement an embedded system interface and a weather clock application. During development, modifying device functionality required close coordination between software and hardware and optimization of the enclosure structure. As resource demands increases, adjustments to the hardware power supply and software optimization become necessary to ensure reliable operation. Internet of things (IoT) device development necessitates a holistic approach. By working backward from the target specifications, hardware, software and enclosure design must be considered together. The results indicate that optimized power supply, low-coupling software operation and a thermally efficient enclosure significantly enhance the long-term stability and low-power operation of IoT devices.
