心率传感器

简介

DFRobot正式推出超小型心率传感器，采用光电容积脉搏波描记法(PhotoPlethysmoGraphy,PPG)，通过测量血液中血红蛋白随心脏跳动而对氧气吸收的变化量来测量人体心率参数。该方法拥有响应性快，性能稳定，适应性强等特点。模块拥有方波和脉搏波两种信号输出模式，可以通过板载开关去自由切换输出信号。脉搏波将输出一个连续的心率波形，而方波将根据心率的变化输出对应的方波。新款心率传感器体积只有拇指大小，可以佩戴于手指、手腕、耳垂等皮肤裸露处。另外，板载的Gravity 3-Pin接口也可直接兼容Arduino I/O扩展板，使用简单，平台兼容性好，可广泛应用于手环，腕带等可穿戴饰品的DIY制作。



注意：

1.此为静态心率传感器，测量时请勿随意移动，也勿按压过紧。

2.本品并非专业医疗仪器，不能作为辅助配件参与诊断和治疗。

3.心率传感器背面的薄膜不能撕掉，撕掉后将造成无法修复的损坏！ |

产品参数

供电电压：3.3 - 6V，推荐5V
输出电压：模拟量（0 - VCC）/ 数字量（0 / VCC）

常见问题

还没有客户对此产品有任何问题，欢迎通过qq或者论坛联系我们！

打开串口监视器没有稳定数值或根本没有数据产生心率传感器使用想要看到稳定的数据
最好是接到手指上并接触压力合适
烧录代码后观察模块上灯闪烁和脉搏跳动一致再打开串口监视器
串口监视器可能不会立刻出现数值请耐心稍等一会
