摘　　要：设计了一种基于多传感器的恶劣天气行人预警信号灯,该信号灯通过PM2.5传感器GP2Y1010AU0F、温湿度传感器DHT11以及红外光栅传感器DQY-4004-NB-NK-PB-PK-J,并以嵌入式智能硬件Arduino为核心控制单元,将智能温湿度数据、PM2.5数据以及行人过街信息进行实时采集,可在恶劣天气环境下极大程度的避免交通事故的发生。In order to design a multi-sensor-based warning signal for severe weather pedestrians,the signal light passes the PM2.5 sensor GP2Y1010AU0F,temperature and humidity sensor DHT11,and infrared grating sensor DQY-4004-NB-NK-PB-PK-J,and embedded intelligent hardware Arduino is the core control unit.It collects intelligent temperature and humidity data,PM2.5 data and pedestrian crossing information in real time,which can avoid traffic accidents to a great extent under severe weather conditions.
