Design of PM2.5 Measurement and Alarm System based on STM32

Abstract

The rapid development of high-tech has brought a lot of convenience to people's life and work, especially the single-chip technology, which is widely used in many sensing devices, and is becoming increasingly miniaturized and diversified. This design mainly uses STM32 single chip microcomputer as the core board, uses GP2Y dust sensor to collect PM data in the tested environment, sends the collected data to STM32 core board, uses the control function of the chip to calculate and process its data, and transmits it to the display to display the data. This design can facilitate people to detect the air quality of the surrounding environment at any time, improve people's surrounding environment and improve their physical fitness.
