We applied sensing principles using sensing technology, redeveloped efficient software using its standardized methods, and expanded the use of networks. The sensing principle and sensing technology can be applied to research and analysis in business processes such as facial recognition, body temperature testing, and automated attendance recording of web technology. On the basis of the results of market demand analysis, we successfully proposed a system to simplify the design, demonstrating the various functions of the attendance recognition software based on web technology. The new system avoids the deficiencies of the old system, making it more innovative. We used software such as HTML, CSS, JS, Django, MySQL, and WeChat programs among multiple frameworks and developments for our system, and used MySQL to store employee facial information, basic personal information, attendance records, personal temperature test results, and health records.
