描述

注： 为必填项 请在报名阶段填写 ↓   <h3 style="line-height: 1.8;"> 1、项目功能介绍</h3> 温湿度检测仪是传感器将测量到的温度和湿度信号转换为电信号，经过电路处理（如稳压滤波、运算放大、非线性校正等），最终输出与温度和湿度成线性关系的电流信号或电压信号，或者直接通过主控芯片进行数字输出的一种电子仪器，在日常生活中广泛应用，可用于气象判断，环境检测，环保等方面。       <h3 style="line-height: 1.8;">2、项目属性</h3> <hr /> 电子设计类项目，未参加过比赛，新手挑战。       <h3 style="line-height: 1.8;"> 3、开源协议</h3> <hr /> 本温湿度检测仪，主要用于环境温度和湿度的感应检测，以STM32G030K6T6芯片为主控芯片，盛思锐温湿度传感器为主要检测模块，SN74HC595PMR芯片为辅组芯片，数码管显示，电池供电，盛思锐传感器负责采集环境的温湿度信息，再通过电路以电信号的形式传给主控芯片，芯片通过烧录的代码而控制各个部分实现自己的功能，芯片对传入的信息进行处理运算，再通过控制595芯片，从而控制数码的IO，完成电信号到数字信息的转换，输出温度和湿度，完成功能。 本代码和硬件可供分享。 开源协议：<a href="https://opensource.org/licenses/GPL-3.0</p&gt" target="_blank">https://opensource.org/licenses/GPL-3.0</p&gt</a>;       请在竞赛阶段填写 ↓   <h3 style="line-height: 1.8;">4、硬件部分</h3> <hr /> 此温湿度检测仪原理并不复杂，采用STM32G030K6T6芯片主控，SN74HC595PMR芯片辅助控制显示屏显示实时的温度和湿度，用盛思锐传感器为温湿度的感应器，将环境温度湿度转化为电信号的方式输入芯片，经过芯片里面已经烧录的代码对电信号进行处理运算，再输出给辅助的芯片，控制显示屏的IO输入高低电平，从而以数字的形式输出温度和湿度。在制作过程中要一步一步地调试代码，确保每一步都没有错，切不可一次将代码全部完成后一起输进去，否则将无法判断问题，同时，焊接不出错是成功的前提，主控芯片虚焊或焊接在一起，将会无法烧录代码，芯片无法被识别到，代码要注意写在BINGEN的后面，防止丢失，注意有些需要宏定义，最后即可完成作品。       <h3 style="line-height: 1.8;">5、软件部分</h3> <hr /> main.c / USER CODE BEGIN Header / /   ****   @file           : main.c   @brief          : Main program body   **   @attention     Copyright (c) 2024 STMicroelectronics.   All rights reserved.     This software is licensed under terms that can be found in the LICENSE file   in the root directory of this software component.   If no LICENSE file comes with this software, it is provided AS-IS.   *   **   / / USER CODE END Header / / Includes ------------------------------------------------------------------/ #include "main.h" #include "adc.h" #include "i2c.h" #include "gpio.h" / Private includes ----------------------------------------------------------/ / USER CODE BEGIN Includes / / USER CODE END Includes / / Private typedef -----------------------------------------------------------/ / USER CODE BEGIN PTD / / USER CODE END PTD / / Private define ------------------------------------------------------------/ / USER CODE BEGIN PD / / USER CODE END PD / / Private macro -------------------------------------------------------------/ / USER CODE BEGIN PM / / USER CODE END PM / / Private variables ---------------------------------------------------------/ / USER CODE BEGIN PV / / USER CODE END PV / / Private function prototypes -----------------------------------------------/ void SystemClock_Config(void);
