Adjustable multidimensional environment monitoring system connected to the cloud

With the rapid development of industrialization and urbanization, environmental pollution and indoor air quality problems are becoming increasingly serious, and the demand for environmental monitoring technology is also growing. The rapid development of IoT technology has provided new solutions for environmental monitoring. Based on the above background, this system provides an integrated environmental monitoring solution, which monitors the temperature, humidity, light intensity, CO concentration, alcohol gas concentration, and smoke concentration of the environment through the STM32H7 microcontroller and Tencent Cloud server interconnection, providing users with accurate and timely environmental information to ensure public health and safe production. The system mainly uses MQ2, MQ7, DHT11, photosensitive and other modules to monitor multidimensional environments in real time, and displays the currently measured parameters on the system monitor. At the same time, through the Guanghetong L610 (GL610) communication module equipped with Qualcomm Snapdragon X55 chip, the system can synchronously upload measurement data to the cloud, achieving interconnection between monitoring systems and mobile applications. The user can adjust the threshold value of each parameter on the application side. Once the measured data of the system exceed the threshold value set by the user, the system will automatically send an alert to remind the user through WeChat official account push and call. The experimental results show that the system has advantages such as high-precision detection, real-time data transmission, intelligent warning, remote control, and data visualization.
