Hi,
I have a project collecting data from sensor and send it to Arduino but in Analogue type, in other words i need the data to be received through Analogue pins of the Arduino not through Digital pins, and i was looking in the net is there a specific shield (TX/RX) can send analogue signal to Arduino ??
Best Regards

What kind of analog signal ? Why can’t you just use the analog input pins on the Arduino itself, no shield needed ?
Sorry i forgot to mention the signal need to be sent wireless because the sensor is far from the Arduino kit.
Search for Xbee.
We still need to know what kind of signals this ‘analogue TX/RX’ means. What frequencies does the signal contain? Or how quickly does the level change? How many samples per second does it need to be represented accurately (considering Nyquist criterium) What resolution does the signal need to be sampled in? (how many steps between absolute 0, minimum and maximum signal level.) Do you really need to sample the analog signal at the receiving arduino, or could it be done at the remote location and sent wireless in digital form.
And what range does this wireless connection need to cover?
If you could tell us more about the sensor itself, then this might also help a bit. I lost my magic glass sphere recently.
This, the above, to be especially noted. If the data is going to be used by the Arduino in any form, it'll have to be digitized at some point. If that can be done just as well at the sensor as at the Arduino, it may be easier to find a way to get the data, w/o additional error, to the Arduino.Valen:

The OP has put the cart in front of the horse. Figure out what the end goals are then figure out how to accomplish them.
FWIW I might GUESS that this thread and question is related to this:
The thread relation sounds very plausible. But like I said, no crystal ball/palantir near me for me to use.
Xbee could be used. It’s sample rate is 1000 sample/sec max. But this needs to be divided if more than one channel is sampled. The resolution would be plenty (1024 bits, max voltage level depending on the xbee series/model).
Not channeling your inner Carnac eh ? :mrgreen:
