- 本系统主要用于旅游景点记录游客人数,并限制旅客的流量。采用红外传感器通过检测人体红外并对通过人数进行计数,通过红外对管将检测到的数据发送至单片机,单片机处理后送至数码管显示,数码管显示的数据即为通过的人数,并通过设定值限制旅客数量。当游客超量是系统将给出相应的提示,禁止游客再进入。以更好的保护旅游景点的生态环境。-This system is mainly used for tourist attractions recording the number of visitors and lim

- 人脉搏跳动的时候,血液的透光性不一样会导致接收器那边接收的信号强弱不一样,因此可以把变化的信号滤波、放大、整形等系列处理后 ,单片机利用外部中断对其进行计数,最终换算成人一分钟脉搏的跳动次数显示在液晶屏上。(When people beat the light transmittance of the blood is not the same there will lead to receiver the received signal strength is not the same, so
