| 针对目前PM2.5检测器检测过于复杂、成本高、精度难以保证的缺点，提出一种基于无线通信模块的户用PM2.5检测器。该检测器由室内机与室外机2部分构成，通过RF1100SE模块实现室内外的通信。室内机与室外机均采用成本极低的STC单片机作为主控芯片，工作时室外机通过光敏粉尘传感器实现对户外PM2.5的检测，并将检测数据由无线模块发送到室内的接收模块，经单片机处理后由LED液晶显示屏显示实时数据和24小时的数据变化曲线，保证人们在室内能够准确获知室外的PM2.5数值，从而为人们对户外空气质量作短时预测，进而为指导人们的出行提供了方便。 |

| This paper presents a PM2. 5 detector based on wireless communication to overcome the shortcomings in the conventional PM2. 5 detector, such as complicated control process, high cost and low detection precision. The proposed detector includes the indoor part and the outdoor part, and the communication is realized by the RF1100SE module. The low cost STC singlechip is used in both indoor and outdoor parts as core chip. The detection of outdoor PM2. 5 is realized by the photosensitive dust sensor in work. And the detection data is transmitted from the wireless module to the receiving module in the laboratory. The LED LCD can realize real-time data display and data changes curve in the past 24 hours after the single chip microcomputer is processed, to ensure that people in the interior can accurately know the outdoor PM2. 5 value, so as to make short-term forecast for the outdoor air quality. It is convenient for people's outdoor activities. |
