Design and implementation of indoor environment parameter collection based on wifi

This topic designs a wireless wide area network and local area network monitoring system for indoor environmental parameters, using STM32 microprocessor as the main control MCU, through general input and output ports, ADC controls temperature and humidity sensors, light sensors, and MQ-7 sensors, and WIFI modules Transfer the data to the mobile APP. Set three different collection points for parameter collection to ensure the reliability of the data, and then transmit it to the server through the network node, and display it on the APP in real-time. When the parameter exceeds the warning value, an alarm can occur. The practical indoor environmental parameter monitoring system designed in this paper, the mobile APP is developed using the Android Studio platform, the server side is developed using the onenet cloud platform, and the data is processed, using email as an early warning method. Through the combination of software and hardware, the automatic collection and wireless transmission of environmental parameters are realized, the cost is reduced, the real-time detection efficiency is high, and the operation is convenient to meet the overall goals and functional requirements of the system design.
