Datalogger using ArduinoJSON and SPIFFS

• To run the program, enter wifi credentials, firebase details in credentials.h
• Compile and run the code in Arduino
• Upload the html/javascript files using this tool https://github.com/esp8266/arduino-esp8266fs-plugin
• Launch the webbrowser at: http://esp-datalogger.local/

• If the esp crashes too much, increase the firebase/SPIFFS timeout

Experimental!

This project is a "proof-of-concept" of a general purpose data-logger using esp8266

• Currently, it allows, browsing files on the esp-8266
• Viewing Contents of CSV Files in the webbrowser
• Download Files from browser
• editing html files using http://esp-datalogger.local/edit

Description

• Data is written to SPIFFS at a certain interval in CSV format
• If filesize of the CSV is greater than set amount, it automatically creates a new file
• Contents are also "pushed" to Firebase

WARNING

As there is a lot going on in the background, esp crashes a lot!!

Hopefully, it can be optimized, so that esp knows do one thing at a time and continue when another activity like firebase update stops

To do

1. View contents of the display CSV File in a graph

• I wrote the code but seems forgot to SAVE!!

2. View Live data using webSockets

• Not sure if live data could be achieved without crashing

Any improvement of code is greatly appreciated so that it won't crash.
