Connection WI FI

Hello everyone, I have an arduino uno and I need to connect to a WIFI AP by to send sensor data, someone can give me a solution to be the shield without wifi arduino?

I found these modules a reasonable price, someone can tell me what the easiest to implement, library that already exist?

What do you think?

That would be like making a phone call without a phone, wouldn’t it?

What you want is far from clear. If English is a second language, there are alternative language sections on the forum. If you really want to connect to WiFi without a WiFi shield, I suggest your only option is to use an ethernet shield that is connected to a WiFi repeater. This option brings its own benefits.

that's not what I mean, I want a wifi module for easy setup library that already exist, like the arduino wifi shield, but it is very expensive, I have tried with xbee wifi S6B, but I'm having trouble to program it, I found these modules a reasonable price, someone can tell me what the easiest to implement, library that already exist?

The solution that's the easiest ald very likely also the most flexible and reliable has already been suggested:

Use a "stadard" Arduin Ethernet Shield and connect it per Ethernet Cable to a small WiFi router. e.g. the TP-Link TL WR703n (or use the 702n or the 3020).

The benefits of this approacha are:

  • less expensive than a single Arduino WiFi Shield
  • You can use all the libraries and Sketches that are written for the Ethernet Shield.

If it has to be small I'd use a CC3000 from Adafruit, but makle sure you'll evaluate what what you want to achieve in detail (what protocols to use etc.) and compare with specs and available libraries.

I use a Teensy++2 and a WIZ812MJ as well as a Teensy 3 connected to a WIZ820io connected to a TP-Link TL WR703n in my projects and it has not let me down.
