Description

一种头戴式PM2.5检测播报装置 技术领域
本申请涉及一种头戴式PM2.5检测播报装置，属于环境检测设备技术领域。
背景技术
PM2.5指环境空气中空气动力学当量直径小于等于2.5微米的颗粒物。它能较长时间悬浮于空气中，其在空气中含量浓度越高，就代表空气污染越严重。虽然PM2.5只是地球大气成分中含量很少的组分，但它对空气质量和能见度等有重要的影响。与较粗的大气颗粒物相比，PM2.5粒径小，面积大，活性强，易附带有毒、有害物质(例如，重金属、微生物等)，且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响更大。
因此，空气中PM2.5的数值是衡量空气质量的重要标准，目前尚无能够实时检测播报空气中的PM2.5数值的装置。
