Hi.
In this example, you just need to go to your ThingSpeak account on your smartphone to consult the data.

Regards,
Sara

Thank you very much for brightening my day!! love u very muchh!!

I use your thingspeak coding to send INA219 current info.

May God bless you..

I want to ask about the lowest time to publish the value. I’m trying to set the timerdelay to 5000 ms but it only send for every 15 s, does the 15 s is the lowest time to publish the value?

Can you please tell me how to adapt this program to to count and record the pulse from an electricity meter using a photodiod or optical pulse detector or any other pulse counting device?
I would very much appreciate it if you give me some guidance in achieving this.
I would like to be able to record this over a 24hr period and longer term to monitor kWh power usage.
Many thanks
Norman Gaskell
