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. AirQ Read more

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

Building a wireless thermostat using Arduino/3

In the second part of this tutorial we added to our wireless thermostat the ability to interact with the user through an LCD display and switches. We can simply increase/decrease temperature using two practical switches and we can see the ambient temperature on the LCD display. We also used an AirQ 100 wireless temperature sensor to separate the Arduino from where we want to detect temperature: this allows us maximum flexibility since AirQ 100 sensor can be placed wherever we want.

We are not satisfied, however: in the Internet of Things (IoT) era there is more to do. We want to control our thermostat by the Internet. And the good news it that it’s a trivial task tanks to Arduino Ethernet shield. Let’s go :-)

Bill of material

For this part of the tutorial we need the following material:

The hardware setup

The hardware setup is almost the same of the second part of this tutorial. There are only a couple of differences:

  • We obviously need the Ethernet shield and we can put it between Arduino and AirQ ShielD (we always suggest to put AirQ ShielD on the top to avoid reduction of operative distance between the shield and other AirQ Networks devices).
  • Since AirQ ShielD uses pin 10 and 11 and these pins are also used by Ethernet shield, we need to rearrange them. So, using a couple of patches, and leaving those pins non inserted in the ethernet shield pin headers, we can rearrange pin 10 and 11 on pin 8 and 9 respectively, as shown in the following photo.

With these two fixes we are ready to add web functionalities to our thermostat :-)

Building a wireless thermostat using Arduino/2

In first part of this tutorial we started developing a wireless thermostat using Arduino Uno and one AirQ 305 control board. In that tutorial we designed a really simple thermostat that doesn’t interact with the user: the desired temperature is fully hardcoded inside the code and user can’t see the ambient temperature. In the second part of this tutorial we’ll push our thermostat to a more interesting level, adding a LCD display and two switches that allow to increase/decrease the wanted temperature. Moreover, we’ll remove the tmp36 temperature sensor attached to Arduino and we’ll use a more practical AirQ 100 wireless temperature sensor.

Bill of material

For this part of the tutorial we need the following material:

  • One Arduino Uno.
  • One AirQ ShielD for Arduino Uno.
  • An AirQ 305 wireless relay board.
  • An AirQ 100 low-cost wireless temperature sensor: different from the fist part of tutorial, we’ll use a wireless temperature sensor since it’s more practical to have the sensor separated from the Arduino. With a wireless sensor we are totally free to place it wherever we need. However, if you need to keep the budget low, you can simply rearrange this tutorial to use the tmp36 sensor.
  • A character 16×2 LCD: we’ll use a cheap 16×2 LCD by Powertip (model PC1602F, which uses a compatible display driver for the Hitachi HD44780 display chip) but you are totally free to use every type of display.
  • Two SPST switches.

Building a wireless thermostat using Arduino/1

Starting from this post, we’ll publish a series of tutorials that show how it’s simple to build custom and complex wireless solutions using Arduino and AirQ Networks products.

heating-systemThe first tutorial we publish is maybe the most simple but it’s the bare bone tutorial of all DIY and makers: a Wi-Fi thermostat. Unless you are one of those lucky people that live in that areas of the earth where there are 25°C during all the year, a thermostat is useful both during winter and summer. During winter a thermostat can control the heating system as well as conditioning system during the summer. But often devices are placed far from where we need to control them. And this is especially true for boilers that are usually placed inside specific rooms (see left picture).

So wireless is a crucial point to design a flexible and adaptive thermostat. But we want to go further. In the Internet of Things (IoT) era, we want to design a thermostat that is smart and that we can control from the web wherever we are.

Bill of material

This tutorial is divided in three parts. In the first part, we’ll design a really simple but functional thermostat able to control a remote boiler according a hardcoded temperature. To do this step we’ll need:

For the second part of this tutorial we’ll need:

For the third part we’ll need:

  • an Arduino Ethernet shield;

In addition to these components, a breadboard and some patches are required. However, you are totally free to arrange the project as you like.
