Design of a portable IoT environmental monitoring system

The rapid development of wireless local area network technology has led to the integration of wireless terminal devices into various aspects of our lives. An outdoor portable environmental monitoring system is developed. At present, most of the environmental monitoring instruments on the market are used in the detection of air, lake, ocean, river and other large-scale systems. Based on this, this article uses an embedded development platform and IoT technology to develop an Android interface in mobile terminals. Users can monitor the outdoor environment (such as temperature and humidity information, lighting information, PM2.5, etc.) in real-time through the network. The device is portable and low power consumption, high test accuracy.
