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.html

1. Optical Heart rate and
PPG monitor
Alex Tien 2014/07/21

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

3. Prototyping

4. Stack up

5. Wiring

6. Optimizing
Shielding, prevent
light leaking
1 mm thick
0.5 mm
1.5 mm 2 mm
2.5 mm3 mm

7. Creating case

8. Assembling

9. Upgrading

10. Video and information
