摘要： 我购买的是这个模块：6.45元/个先解释一下这个模块的原理：人体红外线感应模块工作原理一、红外光谱 人们肉眼看得见的光线叫可见光，可见光的波长为380～750nm。可见光的波长从短到长依次排序是紫光→蓝光→青光→绿光→黄光→橙光→红光。波长比红光更长的光，叫做红外光，或叫做红外线（红外）。红外光是人们无法用肉眼看见的光线。民 部分光线的波长分布如下： 紫光（O.40～0.43μm）；蓝光（0.43～0.47μm）；青光（O.47～0.50μm）；绿光（0.50～0.56μm）；黄光（0.56～0.59μm）；橙光（0.59～0.62μm）；红光（0.62～0.76μm）；红外（0.7... 阅读全文
