成品展示
4 设计原理
PIR传感器：
PIR传感器：一种电子传感器，测量从其视野内的物体辐射的红外(IR)光。最常用于基于PIR的运动检测器。所有温度高于绝对零度的物体都会以辐射的形式放出热能，通常这种辐射对人眼来说是不可见的，因为它是以红外波长辐射，但它可以被为此目的设计的电子设备检测到。
在这种情况下，术语“无源”指的是这样一个事实，即PIR设备不产生或辐射用于检测目的的能量。它们完全通过探测物体发射或反射的红外辐射来工作，它们不能探测或测量热量。
TPA81：
热电堆阵列，检测2微米~22微米内的红外线（辐射热的波长）
同时测量8个相邻点的温度
控制伺服系统来平移模块并建立热成像
检测2米(6英尺)范围内的蜡烛火焰，不受环境光影响
Arduino IDE
电路图：
如果想使用8个PIR传感器，应将8个单个PIR传感器连接到Arduino板上，并逐个读取它们
软件部分
运行Arduino板步骤：
在/en/Main/Software下载操作系统软件，并按照说明安装集成开发环境软件运行Arduino IDE，清除文本编辑器，在文本编辑器中复制下面的代码导航至草图并包含库(从以下链接下载库)，点击添加压缩库并添加库在工具和电路板中选择电路板，选择Arduino Nano将Arduino连接到电脑，并在工具和端口中设置通讯端口按上传(箭头符号)按钮
运行此代码后，在 Arduino IDE 中打开串行终端并查看 TPA81 感应到的 8 阵列温度。每行的第一个数字属于总温度。
要手动定义手势，需知道手部温度，并将其设置为偏移量。
将偏移量设置为 29 度，上传以下一代码查看在 TPA81 前的手部动作。
