Arduino Project Ideas - Part 6
Pulse Monitoring over Wifi
Determine a person's pulse over a Wi-Fi network and display it in a web browser.
- WeMos D1R1 microcontroller (ESP8266)
(Any Wi-Fi Arduino-like unit will work)
- KY-039 Pulse Monitoring module
- 3 connecting wires
Great experiment for Tele-Medicine!
Your sketch will need to be calibrated to the pulse module. An inexpensive retail finger-pulse monitor can help with this(or do it the old fashioned way!).
The basic KY-039 source code can be found here
The basic ESP8266 Web-enabing source code can be found here
Someone in the hospital having a birthday? No open flames allowed?
Here's a solution!
HC-12 Wireless Texting
Texting may not have been what the creators of Arduino had in mind.
Use two Arduinos with two HC-12 Wireless Serial Communications Modules to build yourself a wireless text app that works up to 1.8km apart!
