Portable Environment Detection Device

With the development of urbanization and industrialization in our country,the consumption of energy is increasing,and the problem of environmental pollution is becoming more and more serious,which affects people’s daily life.The traditional environmental monitoring system(temperature detection system,PM2.5 concentration detection system,UV intensity detection system)is often embedded in the data acquisition system of central station,via wired or artificial periodic card way to complete data collection,from a technical point of view,there is a high cost,sensitivity and accuracy of monitoring area is relatively poor,blind the problem.Therefore,it is very meaningful to study a more intelligent,real-time and integrated portable detection device.In this paper,the design of portable environmental monitoring device is controlled by STM32F103C8T6 chip,which can be used to collect environmental temperature,PM2.5 concentration,UV intensity data,and display the LCD screen.And use the Internet technology in the design,so that the detected data is transmitted to the center for information management,analysis and comprehensive treatment,can improve the efficiency and real-time environmental monitoring,to provide the basis for decision-making.This paper mainly from the following aspects:(1)in the detection of environmental parameters,the detection principle of different detection methods are introduced.(2)the hardware circuit of the detection device is designed,including the power module,the minimum system module,the data acquisition module,the display module and the wireless transmission module.(3)designing software program for debugging.Finally,the data acquisition,processing and transmission are realized.
