Design of Cabin Environment Perception Module Based on CS32

A cabin environment perception module based on the CS32 MCU is designed, adopting a fully domestically produced design. It uses the LC75 temperature sensor, PRT1-330 digital pressure sensor, and GXHTC3 temperature and humidity sensor to collect temperature, humidity, and pressure data inside the cabin. The CS32 MCU collects temperature, humidity, and pressure data from the sensors via the IIC bus and reports the data to the host computer through the serial interface USART, achieving real-time monitoring of temperature, humidity, and pressure data inside the cabin. Additionally, a bootloader program for updating the program via the serial interface USART is designed, allowing program updates through the serial port [1].
