In daily travel, there are numerous instances of car windows causing injuries through pinching. Based on this, this article proposes a study on the anti-pinch function of car windows using a microcontroller. This study uses the CC2530 microcontroller as the main control chip, employing a pressure sensor to detect the pressure on the car windows, and periodically collecting data. When the detected pressure exceeds a preset value, the car window is controlled to retract appropriately. Additionally, a coordinator node is used to connect to a WiFi communication module to enable remote control of the car window. This design allows for intelligent control of the car window based on the pressure detected, and users can also remotely control the window raising and lowering through their smartphones. This achieves intelligent, wireless, and networked control of car windows, offering a very broad development prospect.
