Survival guide for AirQ ShielD buyers

You just received your new AirQ ShielD. And you want to start developing your application right now. But before you can start coding there are a couple of things you may know. We know: you don't like to read Read more

sNET library for Arduino now on github

After a week of testing and tuning up, we are finally ready to push the Arduino sNET library on our github account at http://github.com/airqnetworks :-) The library repository is named snet-arduino, and it can be easily downloaded using git: $ git clone Read more

New AirQ ShielD for Arduino UNO

As we've announced some days ago, we are progressively releasing information about how to develop custom applications above our wireless devices. We already described the protocol we've developed to interact with our control boards and wireless sensors: its name is sNET Read more

New wireless control board from AirQ Networks

We are really excited to announce that we are almost ready to release a new control board on the market. Its name is AirQ 305 and it will have really interesting features and, more important, a really competitive price.

airq305-1

AirQ 305 has the following characteristics:

  • 4 Relays capable of control up 10A of current.
  • 4 Opto-isolated inputs that accept a broad range of inputs running from 3V to 24VDC.

 

Different from other AirQ Networks control boards, that are designed to address the industrial market, this control board was designed to keep its production costs as low as possible. So AirQ 305 is addressed especially to hobbyists and all those people that need to keep budget low.

AirQ 305 will be sold for a limited time offer at €49,90. Special offer is available only if the AirQ 305 is bought in bundle with an AirQ ShielD.

We’ll start to ship AirQ 305 control boards by the end of the next week (15 March 2013).

How to use AirQ ShielD to build custom wireless solutions

A lot of you asked us if AirQ ShielD could be used to build customs hardware solutions without using other AirQ Networks devices. And the answer is definitively yes. AirQ ShielD is nothing more than a transceiver and it is designed to accept commands that send bytes to another AirQ ShielD. To develop a wireless solution using AirQ ShielD you need:

  • At least two AirQ ShielDs (but you can use how many you need).
  • Two Arduino Uno boards.
  • The sNET library for Arduino

AirQ ShielD allows sending data messages to another AirQ ShielD. The maximum number of bytes that can be sent is 10. To a send a message to another shield the sNET::sendToDevice() method can be used. Let’s do an example. Suppose that you received two AirQ ShielDs: one with sNET address equal to 191.0.0.11 and the other one with the address 191.0.0.12. And suppose that you want to send the “HELLO” string from 191.0.0.11 board to 191.0.0.12. The following Arduino code is all you need.

The code is self-explanatory: the first 4 parameters are the address of the remote shield that will receive the message; the fifth parameter (0x1) says sNET library to send a data message; the remaining part is the data we want to send and its size. If you want to send a message to all AirQ ShielD on the same sNET network, you can use the sNET::sendBroadcast() method:
