In this tutorial, we are going to make an IoT Heart Rate Monitoring System using Arduino. It will detect the heart rate using the Finger-clip Heart Rate Sensor. Then, every 1 second, it will send the readings to Blynk server using the ESP8266 Wi-Fi shield. So, the heart rate can be monitored through your smart phone from anywhere in the world over the internet.
This video shows how to display heart rate data to IoT platform Blynk using Maker UNO (Arduino Uno compatible).
This is the list of items used in the video.
This is Arduino sample program to read heart rate through finger using Finger-clip Heart Rate Sensor. Then it will send to Blynk server every 1 second. Please install following libraries.
- Blynk by Volodymyr Shymanskyy V0.6.1 (Library Manager)
- BlynkESP8266 by Volodymyr Shymanskyy (Zip) – https://github.com/vshymanskyy/BlynkESP8266
