With the continuous development of urbanization, people face more and more environmental problems in their daily life, such as declining air quality and serious environmental pollution. Therefore, in order to solve these problems, environmental monitoring equipment has gradually attracted people’s attention. The WIFI environmental monitoring equipment introduced in this paper can be connected to the Internet through WIFI, so as to realize real-time monitoring of various environmental data such as air quality, temperature and humidity, and provide people with more accurate and convenient environmental monitoring services. Therefore, the research of this paper has important practical significance and social significance. The WIFI environment monitoring equipment designed in this paper is mainly composed of STM32F103C8T6 MCU, DHT11 temperature and humidity sensor, MQ-2 smoke sensor, acousto-visual alarm module, WIFI module and so on. Among them, STM32F103C8T6 MCU as the core component of the whole device, responsible for collecting and processing sensor data, and upload the data to the Internet platform through the WIFI module. Through the actual test, this paper proves that the WIFI environment monitoring device has the following functions: through DHT11 detection of temperature and humidity, when the temperature and humidity exceeds the threshold, the audible and visual alarm module will issue an alarm. Through MQ-2 detection of smoke value, when the smoke value exceeds the threshold, the audible and visual alarm module will also issue an alarm. The device can be connected to the Internet platform through WIFI, and real-time monitoring data can be uploaded to the Internet platform, and users can view environmental data in real time through the Internet platform. The WIFI environment monitoring device based on STM32F103C8T6 single chip microcomputer designed in this paper realizes the real-time monitoring of temperature, humidity and smoke values, and has many functions such as sound and light alarm and WIFI data upload. The equipment price is relatively low, has a certain price advantage. The research of this equipment is of great significance for solving urban environmental problems and improving people’s quality of life.
