The background of this project is to monitoring human body heart rate and send an alert to email when heart rate above normal condition (in this case I set 200, because it’s very noisy).
Will try to add something like capasitor to decrease the noise and make it wearable.
Yes sir, lag in the graphical draw for live monitoring.
But I think, it’s because the latency.
It’s very slow in my country, building a mirror server here very recommended.
I do appreciate the feedback, it’s something we’ll be looking to actively improve as we grow as a platform. We’re even considering options like standalone cayenne servers, so you could even host the dashboard on your local network if latency was a major issue.
Standalone server is ok. In my mind, Cayenne should produce IoT devices, so people that didn’t have knowledge about programming can enjoy the tech improvement in their life. Just do simple step to setup the devices and it automatically connect to the server. My opinion, there is more consumer than technician/electrician/programmer. So the maintenance cost can be handle by profit of selling products and absolutely who expert on code can build themselves version.
It’s only my opinion sir, I’m happy if it give an idea to the company.
Hi there, Im about to do this project as well,but unfortunately the program doesn’t s seem to be correct for nodemcu since the library used for that board used MQTT cayenne library, or is there any way to merge this library? i tried a lot of examples to make this project works,but seem to found tons of error
you are using old cayenne library. have a look at this Adding a New Device using MQTT and first add your device to cayenne.
Next you try to get your heart rate value on your serial monitor without the cayenne code. Once you get the value, add the code for OLED and get it working. If you get both this working you can add the cayenne code and display the value on cayenne dashboard.
