随着海南建设国际自由贸易港的逐步推进，海南岛生态环境质量越来越得到广大岛民的高度重视，建筑施工产生

的扬尘污染和噪声污染、生产生活产生的空气污染、废水排放引起的水环境污染等都给海南的生态环境带来了巨大挑战。该生

态环境监测系统采用集成式传感监测，具有同时监测温度、湿度、PM2.5、噪声、风向以及风速，并能够通过按键设置PM2.5含量

上限值并联动声光报警等功能。采用STC89C52单片机作为中心处理模块，C语言作为开发语言，Keil 软件编写及调试程序。

With the gradual advancement of Hainan's construction of an international free trade port, the ecological environment quality of Hainan Island has been paid more and more attention by the majority of islanders. The dust pollution and noise pollution

caused by construction, air pollution caused by production and life, and water environment pollution caused by wastewater discharge

have brought great challenges to the ecological environment of Hainan. The ecological environment monitoring system adopts integrated sensor monitoring, which has the functions of monitoring temperature, humidity, PM2.5, noise, wind direction and wind

speed at the same time, setting the upper limit of PM2.5 content by pressing the key and linkage audible and visual alarm.

STC89C52 single chip microcomputer is used as the central processing module, C language is used as the development language,

Keil software is used to write and debug the program.
