Dear all, I am using the micro:bit with ESP-01s and the CO2 sensor to monitor indoor air quality. Thingspeak cannot show the data eventhough the ESP is connected to the wifi (checked with the router). Failed to talk to my ESP even I have setup a new channel many times. Can anyone advise me what to do?

Thank you for your help in advance.

I'm accessing internet on my Arduino uno using esp-01, is there a thingspeak Library i can use on this to send data to my thingspeak channel.
