I want to send ECG sensor data from raspberry pi using python 3 to Thingspeak channel.
Thingspeak encounters the following problems:
* Thingspeak channel gets updated once every 15 seconds, which is too low for ECG signal that is sampled at 1KHz frequency.
* For high data update speed, thingspeak ask for payment.
How to send the data on a high update rate to Thingspeak?
Please recommend any free platforms like Thingspeak, so that I can send my data?
dear Sumair,
you need a high frequency channel, i don't think it could be possible with "share thing" IOT platforms! so i suggest you process data locally and then send the results to the sites.
nevertheless, you can check alternatives for Thingspeak at:

Hi
Please check the following work. It describes the process in details. I believe it will help you.

Hi,
You can use google sheets for this purpose as Thingspeak will ask for a payment to reduce delay.
Use JSON (JavaScript Object Notation) to upload data from the sensor to google sheets. You can expect a delay of 1 sec.
You can find multiple tutorials in youtube regarding uploading sensor data in google sheets using JSON.
