Hello
I would like to have some suggestion to select a WIFI module to be use with Arduino Uno. I know nearly nothing about WIFI / Ethernet protocol and characteristics. Still not vary familiar with Arduino capacity and limitation.
The goal is to send a report to a web page
What should I look for?
Any informations appreciated
Martin.
P.S. Excuse for my English. More fluent in French. 
Don't use Uno + WiFi module. This makes life more difficult. I suggest a Wemos D1 Mini.
An arduino with a wired Ethernet board is pretty straight forward to setup and use. You might start with that before moving to a wireless setup.
Resolved:
Thanks for your input. I ordered an Ethernet shield. If I need to go WIFI, I will try the Wemos D1.
Good suggestion, I will learn to walk before running.
