Desktop temperature and humidity measuring instrument

I. Project Overview
 
This project aims to design and implement a simple desktop temperature and humidity meter based on an STM32 microcontroller. This meter accurately measures the temperature and humidity of the surrounding environment and displays the data intuitively on a screen, providing users with real-time environmental information.
 
 
II. Hardware Components
 

STM32 Microcontroller: As the core of the system, it is responsible for data acquisition, processing, and control display.
Temperature and Humidity Sensor: A temperature and humidity sensor module is selected to accurately measure ambient temperature and humidity and transmit the data to the STM32.
Display Screen: A digital tube display is used to show temperature and humidity data and other relevant information.
Power Supply Module: Two AA batteries provide a stable power supply for the entire system.

 
 
III. Software Design
 

Driver Development: Drivers for the STM32 microcontroller and peripherals such as the temperature and humidity sensor and display screen are written to realize data acquisition and display.
Data Processing Algorithm: The acquired temperature and humidity data is filtered and calibrated to improve measurement accuracy.
Low Power Consumption Design: The software algorithm is optimized to reduce system power consumption and extend battery life.
