Hello everyone,
I want to read Noise&CO values using Arduino UNO and then send this to Thingspeak. I am coding it using the Arduino IDE 1.6.7 with the Ethernet add-in module.
I have managed to write some code that reads and displays my data, and I have written some code that reads the data and sends it to Web Server,But in case of things speak my data not going to "Things Speak" .Which I want use for analysis...please help me..
Any suggestions?

Did you check out the Arduino examples on the thingspeak website (under Support).
I think there are some examples in https://github.com/mathworks/thingspeak-arduino

Hi
Thanks for Replay
Yeah.....I have tried(checked) those example's, but not working properly in my case.....
I have changed my MAC address, Things Speak Channel Number and writeAPI key, but my data not uploading into Things Speak....
Please...give me suggestions...what i do now???

What happens if you only try and upload 2 or 3 voltages instead of 8? I seem to recall reading that someone else had strange troubles when attempting to upload 8 fields at once.
If its the case it must be a bug in the thingspeak arduino library since its definitely possible to upload all 8 fields.

Hai...
Thank You....=>rw950431
It's working fine now......data uploading into my fields(Things Speak Channels),but i'm not getting channel updates(i.e ..in channel status updates)
how to get it???
any suggestions....?
Thanks in advance

Hi,
I don't see that you are updating the channel status field. You are only updating the fields in your channel. To update the status field you have to send a HTTP POST request to ThingSpeak (I am not sure if the ThingSpeak Arduino library support updating the channel status). For more details on how to format your POST request you can see here.
