Hi Arduino fellows,
I did not want to ask this question hoping to figure out what the problem is but I simply cannot figure it out. I am using Arduino UNO and WIFI 101 as a slow control which sends data and the plot to a web server. Then I use a data php file which takes the data from the web page in strings and sends them into a SQLITE3 database. Other php readout file reads them from the database and then sends them into an html page. What I cannot understand why the Arduino server with the data sometime goes blank which results in zero results and the sensors spike to zero. My plot looks awful. Cannot this thing maintain stable data readout so my plot will be damn flat. Please advise what can be the reason of this instability. The plot and the data page are attached...
