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.

Awesome project
what is the white wire(micro usb) on the ESP8266 connected to
Adafruit 12C .h no such file or directory like this error coming while compiling...
Plz help me out!¡!
when I upload the code to the Nodemcu I am getting Leaving Hard resetting via RTS pin. who can I solve
Can I use esp32?
Please guide for esp32?
5:35 I cannot open the 2 serial monitors side by side and see each reading. Once I change one the other one will also stick to the current one.
First close both the ino files. Go to the sketch location and open the sketch file from there. It will work. Try it.
It doesn’t work if you creat a new file from the already opened sketch.
👏👏👏
Instad of using arduino+esp8266 why you don't use only esp32 that will replace both ???
The sensor doesnt work directly with esp32 or esp8266
I am Getting Adafruit on Oled display please mam suggest what to do ??
Yes ma'am plz help!!!
Screen is displaying only adafruit what to do?
Plz reply🙏🏻🙏🏻
Does your this error solved ??
OLED screen just displaying Adafruit and its logo and no result get published.
Can i use arduino uno instead of nano???
Yes
Screen is displaying adafruit can you help me with this issue??
Please!!!
I am also getting the same problem. If you have resolved it then please tell what to do?
5:39 after WiFi connected then IP address 192:168:0:195
I am getting
-----CUT HERE FOR EXCEPTION DECORDER----
Then displays
Software WDT reset
>>>>>stack>>>>>>
ctx: cont
sp: 3ffffd00 end: 3fffffc0 offset: 01a0
So mdm can you help me solve this problem. I am not getting the Attempting MQTT connection.
Hey I got the same error. How did you solve it??
Where to purchase this sensor ??
You can purchase it from graylogix.in
Great project ♥👌
but why using Arduino !!! Esp8266 has Analog input pin.
I have same question
The pulse senOr doesn’t work with NodeMCU due to some timer issues.
I am the first on comment. Awesome 👌
Awesome project
