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：https://opensource.org/licenses/GPL-3.0 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);
