Handheld detector (based on Liangshan School)

Project Introduction:
This project is based on an environmental monitoring expansion board project, with slight modifications.
Expected Functionality
: Basic Functions:


Temperature and humidity sensor: for detecting temperature and humidity data;


Barometric pressure sensor: for detecting atmospheric pressure data;


Harmful gas sensor: for detecting harmful gases and other data;


Screen: for real-time display of collected data;


Wireless communication: for sending data to receiving devices.


Desired Additional Functionality (Under Development):

Compass,
leveling instrument, distance measuring instrument , illuminance detection
circuit design. For basic circuit design and functional circuits, please refer to the official case study. Other functional circuits of the environmental monitoring expansion board will be explained after testing (the remaining modules are mostly I2C communication, and their circuit reference value is not significant). Currently, the project runs the official code correctly. I am currently learning LVGL interface development and debugging the remaining modules for physical verification.
