ESP32 Data logger & Data History displayed.
Бюджет $10-40 USD
My project is for an ESP32 data logger and data history display. I need to log serial data from a sensor, which will be displayed in the form of a chart on a html [login to view URL] data will then be stored in an SD card for future reference. I am looking for a freelancer with expertise in this project.
I have a working sample.
The esp32 is on APmode, uses a sd card to store the requested data from a sensor. The ESP32 host a webpage that users can log in and see the data stored, data is pulled from the SD card via http request on a file called data.txt. My problem is as follows:
The chart only displays 20-40 data points stored.
But if there is more, like weeks or month worth of data points it freezes or re-starts. I figured it has to do with the amount of time the http request takes due to the large amount of time it takes to generate the response.
So, I thought!
Why not download the whole file like an attachment on the user device and then read that file ([login to view URL]).
Let me know your thoughts!!
