描述
DFRobot 微型心率血氧飽和值感測器 Heart Rate Sensor 類比/數位雙輸出
DFRobot正式推出 DFRobot 微型心率血氧飽和值感測器 ，採用光電容積脈搏波描記法(PhotoPlethysmoGraphy,PPG)，通過測量血液中血紅蛋白隨心臟跳動而對氧氣吸收的變化量來測量人體心率參數。該方法擁有響應性快，性能穩定，適應性強等特點。模塊擁有方波和脈搏波兩種信號輸出模式，可以通過板載開關去自由切換輸出信號。脈搏波將輸出一個連續的心率波形，而方波將根據心率的變化輸出對應的方波。
DFRobot 微型心率血氧飽和值感測器 體積只有拇指大小，可以佩戴於手指、手腕、耳垂等皮膚裸露處。另外，板載的Gravity 3-Pin接口也可直接兼容Arduino I/O擴展板，使用簡單，平台兼容性好，可廣泛應用於手環，腕帶等可穿戴飾品的DIY製作。
注意：
1.此為靜態心率傳感器，測量時請勿隨意移動，也勿按壓過緊。
2.本品並非專業醫療儀器，不能作為輔助配件參與診斷和治療。

Heart Rate Sensor
The DFRobot heart rate sensor is a thumb-sized heart rate monitor designed for Arduino microcontrollers. It includes a Gravity interface, for easy plug-and-play connectivity.
This sensor is a pulse sensor which is developed based on PPG (PhotoPlethysmoGraphy) techniques. This is a simple and low-cost optical technique that can be used to detect blood volume changing in the microvascular bed of tissues. It is relatively easy to detect the pulsatile component of the cardiac cycle according to this theory.
The sensor has two holes that you can use to attach to your belt. You can wrap on your finger, wrist, earlobe or other areas where it has contact with skin.
The heart sensor has two kinds of signal output mode: analog pulse mode and digital square wave mode. You can change its output mode using the dial switch. There are many user scenarios, including education, sport or maker/interactive projects!
Specification
- Input Voltage (Vin): 3.3 – 6V (5V recommended)
