一种基于单片机的蓝牙环境监测系统设计(论文10300字)
摘要：雾霾天气逐年增多，导致各地方百姓易得各种肺炎等呼吸道疾病，使民众幸福感降低，生活质量直线下降，尤其是各个省会城市，空气质量的高低对于人们有着越来越重要的意义。中国各地已经将雾霾浓度当作一项重要指标作为灾害警报。雾霾是由PM2.5、PM10、PM0.1以及重金属颗粒组成[1]。自从第一次工业革命以后，全球雾霾天气逐渐增多，先开始从英国开始蔓延，不到短短的几十年，英国便成为了著名的“雾都”，这短时间内雾霾带走了成千上万人的生命，而待到发现时已经事态严重经历了近百年的恢复才得以解决。因此，对PM2.5的检测显得越来越重要。本系统以51单片机为核心，由GP2Y1010AU0F飞尘传感器检测大气粉尘颗粒浓度，DHT11传感器检测大气的温度以及湿度的实时数值，LCD1602显示屏将测得得数据显示出来。再利用蓝牙模块将数据传输到手机端显示实时得空气质量，该设计电路精简、性能良好、模块化程度高，误差小，测量阈值范围广，可用于日常生活当中。

Design of Bluetooth Environment Monitoring System Based on Single Chip Microcomputer
Abstract：Haze weather increased year by year, leading to the local people are easy to getvariety of pneumonia and other respiratory diseases, so that people's sense of happiness, quality of life plummeted, especially in various capital cities, the quality of air for people have more and more important significance. Haze concentration has been used as an important indicator in China as a disaster alert. The haze is composed of PM2.5, PM10, PM0.1 and heavy metal particles. Since the first industrial revolution, the global foggy weather gradually increased, began to spread from the UK began, less than a few decades, the British has become the famous "fog", this short haze away The lives of thousands of people, and until the discovery has been a serious experience after nearly a hundred years of recovery was able to solve. Therefore, the detection of PM2.5 is becoming more and more important. The system to 51 single-chip as the core, by the GP2Y1010AU0F fly dust sensor to detect atmospheric dust particle concentration, DHT11 sensor to detect atmospheric temperature and humidity real-time values, LCD1602 display will be measured data show. And then use the Bluetooth module to transfer data to the mobile phone to show real-time air quality, the design of the circuit streamlining, good performance, high degree of modularity, small error, measurement threshold range, can be used for daily life.
Key words：environmental monitoring, PM2.5 concentration, Bluetooth module, LCD display, temperature and humidity sensor
