optical heart rate and ppg monitor
DESCRIPTION
利用綠光LED與light sensor偵測血液流量的變化,來判斷心跳,與利用OLED螢幕顯示脈波。 Use pulse senosr form http://pulsesensor.myshopify.com/ and OLED display shows up heart rate and PPG waveform http://alextien1974.blogspot.tw/2014/07/optical-heart-rate-and-ppg-monitor.htmlTRANSCRIPT

Idea
• Use Pulse Sensor Amped sensor module• Use OLED 128*64 display• Use Arduino Pro Mini• Shows heart rate and PPG waveform
