PIR Motion Sensor | HC-SR501 | Arduino: In this project, we will make a LED to turn on when the PIR sensor detects infrared light. As you may already know humans, emit thermal radiation but we don't see it because most of its spectrum is in the infrared
Remember you don’t need to copy this out by hand or even copy it from the code window as all of the code for this article is in the Resources box at the bottom. Once you have the sketch compiled and loaded to your Arduino the fun starts! You should observe the red LED (the “wa...
HC – SR501红外人体传感器采用被动红外(PIR)技术,通过比较两个热释电红外传感器接收到的红外辐射差异来判断是否有人体存在。其具体工作过程如下: 红外感应:模块内部搭载了一个红外传感器,该传感器能够感受到人体所产生的红外线辐射。当有人体进入到模块感应范围时,红外传感器会感知到人体发出的红外线信号。
