手表底壳正中间黑色区域是PPG心率传感器,通过追踪可见光(绿光)在人体组织中的反射,采集手臂血液流量的波动信号,结合精密算法,来检测您的心率数据。
PPG心率传感器其中两个开孔是LED(发光二极管)器件,在测量心率时会发绿光,测量血氧时,一个会发绿光,一个发红光;另外两个是PD(光电感应二极管)器件,收光使用,不会发光。![](/img.php?b=https://iknow-pic.cdn.bcebos.com/0b46f21fbe096b63954bbacc1e338744eaf8acd8?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_450%2Ch_600%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto)
