Abstract: To enhance the flexibility of vehicle sunroof control, the paper introduces a sunroof control system that leverages the WeChat developer tools and the HC-42 Bluetooth module. By using the JavaScript programming language, a WeChat control program is developed to facilitate automatic mobile phone connectivity with the in-car bluetooth system. Users can manipulate the sunroof's opening and closing through a user-friendly interface, allowing it to be positioned at any point along its track. Through the test of the real car sunroof, the results show that the system has a good control effect on the sunroof, which greatly improves the mobility of the sunroof to a large extent, and has certain practical value for the Internet of things, especially the development of vehicle's intelligentize.
