Smart heart rate monitoring system

In this project, a real-time heart rate measurement technique called Photo-Plethysmography (PPG) is implemented using simple infrared transmitter and receiver circuit.Arduino Uno board has been used for calculating the heart rate from the fingertip. The obtained heart rate values are initially displayed on a Liquid Crystal Display (LCD) and sent serially to Raspberry Pi which is used as an Internet of Things (IoT) gateway. The values are then sent to the cloud through Message Queuing Telemetry Transport (MQTT) protocol. The designed system updates the user with their heart rate through electronic mail (email), Short Message Service (SMS) and real-time plots and provides name and address of a nearby prominent hospital in case of an emergency.
