Hi, I'm very new to Thingspeak but I've got a distance sensor working with an Arduino Uno / Ethernet W5100 card and it is sending distance data nicely to a Channel on Thingspeak. I want to create a Thingspeak App that will read this data and convert it to a volume, after defining some tank measurements. I think I've managed to create this as it returns a volume when I run the app but it only gives me this one reading on the app output, and Channel graph. It doesn't update. Is there an obvious reason for this?
You can use a time control to schedule your code to run at regular intervals. If the output of the code is written to a channel, the regular ThingSpeak plot for your channel field data will be updated as often as the time control runs. Have a look at the second part of the Getting Started tutorial, analyze your data. The part at the bottom talks about scheduling your code. Let us know if that is the result you are looking for. Welcome to ThingSpeak!
That's perfect thankyou. I think it works, It has returned a few 5 minute interval readings to the channel now. I feel a bit (very) stupid as I saw the option for scheduling but glossed over it, as I assumed the channel would run at the same frequency of readings as the one I'm reading off. Thanks for the help.
