摘要
传统的OLED显示编程繁琐,开发复杂,USART HMI屏开发界面友好,利用上位机进行界面开发,可以直接同步到屏幕上显示。系统采用STM32F407作为控制芯片,选用DHT11作为温湿度采集的传感器,最终将采集的温度以多元化的方式显示在HMI串口屏上。如果温湿度不符合设定要求,蜂鸣器就会启动报警。系统经测试,开发容易,工作稳定可靠。
The traditional OLED display programming is complicated and complicated to develop. USART HMI screen development friendly interface, the use of host computer interface development, can be directly synchronized to the screen display. The system uses STM32 F407 as the control chip and DHT11 as the sensor for temperature and humidity acquisition.Finally, the collected temperature is displayed on the HMI serial screen in a diversified manner. If the temperature and humidity do not meet the set requirements, the buzzer will start the alarm. The system has been tested and developed with ease and reliability.
