multiple signals to single Aruino

Other Hardware Sensors
1

Hi
I am very new to Arduino.
I have 3 different sensors connected to 3 different zigbee and each sending signals to Ardunio uno. my question is what if the Ardunio receives the signals from 2 or all (in this case 3) zigbee at a same time. Can it handle it?

Thanks

you can Software serial library for interfacing. We can communicate with 2 . But not sure Whether we communicate 3 zigbee module

You can't use more than one instance of software serial at any one time.
Your best bet is to use a Mega, that has four serial ports.

thanks,
so let me ask it this way.
Xbee that acts as a transmitter that is not connected to arduino board but has a temperature sensor on it. If temperature goes above X degree, then only transmit data to the xbee that acts as a receiver on the arduino uno board?

It may be possible to do what you want but it might be easier and safer to have the transmitter regularly transmit, and the receiver makes use of the data or not as required. That relieves the transmitter of any decision-making but still assures the receiver that it is working OK.

Check the Xbee specs,

This one for instance has multiple channels and may do what you need without the need to have the master poll the slaves for their status to keep things in sync.

thank you all for the info. This is enough to get me started. I am sure I will have more questions coming soon and I know I am in a right place to get answers
