mBlock & Arduino(14)使用人体动作感应器 被动式红外线感应器(Passive Infrared Sensor, PIR)也经常被称为 PIR动作感应器(PIR Motion Sensor),是一种可侦测红外线的感测器,生活中许多物品都会发出红外线,而 PIR 主要是侦测人体发出的红外线变化,来判断是否有人体移动发生。 相对于被动式红外线感应器的是主动式红...
将Arduino 开发板连接到计算机上。 在Arduino IDE 中选择正确的 Arduino 开发板和端口。点击“上传”按钮将代码上传到 Arduino 上。 测试 在PIR 传感器前面挥一挥你的手,当有运动检测到时,LED灯将亮起,并在串口监视器中显示“Motion detected!”的消息。确认传感器检测到了手的移动。如果你一直挥动你的手,信息将...
基于PIR传感器的电路图 带Arduino的PIR传感器设计 描述 PIR传感器,全称“Passive Infrared Sensor”,又称“人体红外线传感器”,是一种能够探测人体热量的电子元件。它通过检测周围环境中的红外线辐射来感知人体的存在,因此被广泛应用于安防、智能家居、自动化控制等多个领域。以下将详细阐述PIR传感器的定义、工作原理、结构...

复制代码并将其粘贴到您的Arduino IDE，然后编译并最终将其上传到Arduino开发板。
Moving on to the Arduino loop function, we will handle there the detection of motion. But, as we have stated before, we don’t want to be constantly polling the sensor or wasting CPU cycles verifying some variable signaled by the interrupt. ...
