I built a project with an Arduino UNO. It’s controling a device
and monitoring 4 different sensors and it’s working well.
Now I need to send the data sensors to an iPhone so in order to
monitor my device remotely.
I need a 200 or 300 feets away range so Bluetooth is not good.
I would like to use an ESP8266 as a Wi-Fi transmitter to send the
data from/to my Arduino UNO.
It can be sent to IO.Adafruit but I don’t know how.
I found a lot of examples on the net but it involve the ESP8266 alone
with the sensors connected directly to the ESP8266.
That’s not good because my project is already working with the UNO.
So I need a way to do that using the ESP8266 as a wi-fi transmitter.
