Lightweight Wireless Heart Rate Monitor

By

Mohammad Alshahrani and Ivan Vargas

This project entails using light sensors and red/infrared LED lights with the help of a microcontroller to count heart beats though one of the users fingers. The microcontroller then takes this data and sends it over Bluetooth to the user's phone where an app is used to connect to the Bluetooth module and then display the heart rate that is being detected. The technologies implemented are Bluetooth and android app development. The sensing was taken care of by a MAX30102 and the calculations were done on an Adafruit FLORA microcontroller. Some future improvements would be adding iOS support and preventing the microcontroller from flooding the Bluetooth module with too many requests which tended to stop communication between the Bluetooth module and the app. One last improvement would be to create a more user friendly UI as currently it is a bit rough around the edges for the average user.
