In one of my previous projects, I explained how you can use the easy pulse sensor with Arduino to measure the Pulse Rate or BPM Value. I also displayed the BPM Value on OLED Display. The Pulse Sensor has a clip that can be easily fitted on the finger. But this time I got another Sensor similar to the previous one. The only difference was, instead of putting the finger into the probe this time we will attach it to the ear lobe. So this is an ear lobe Pulse Sensor that is highly accurate and can be used for learning purposes.
This time I will like to use this sensor with NodeMCU ESP8266 Board and using some Cloud Server I want to monitor it online. So I preferred the MQTT Protocol for sending the data to Server. The best MQTT Platform I have been using for a long is the Ubidots. Using Ubidots you can visualize and analyze the sensor data from any part of the world. So let us learn in detail how we can use this pulse sensor with ESP866 & display the BPM value both on OLED Display as well as Cloud.
