Cool Wave - Project Summary

Cool Wave - Project Summary

Cool Wave is a simple system that can be constructed by almost anyone in almost any location to mitigate the effects of a heatwave. It does this while avoiding the carbon emissions caused by using traditional air conditioning.

This final Summer of Green Tech Design Challenge blog post is to summarise progress and provide an index to the other blog posts from the last month. I will also post any update to the project here after the challenge has finished.  If you want to link to the project as a whole this is a good post to use.

The posts I have written are…

1) The Heat Reduction Concept - A summary of the problem and how I planned to help mitigate it while reducing carbon emissions.

2) Setting up the Seeeduino XIAO - Some updated instruction to set up the microcontroller used in the project

3) Using the DHT20 in MicroPython on the Seeeduino XIAO - A tutorial in using the DHT20 temperature sensor that is to be used in the project

4) Testing temperature sensors for use with the Seeeduino XIAO - Testing and evaluation other temperature sensors for the project

5) Assembling The Electronics - Combining all the project parts in to one functional prototype

6) The Physical Build - Converting the desktop prototype to a physically installed prototype

7) The Firmware - A breakdown of the project software

So, that is the project done, for now. In the northern hemisphere we are not expecting any substantial heat until next summer so practical testing is not possible just now. Simulated summer testing using a hair dryer (and no I am not joking on that one) has been successful. I still have some tidying to do and improvements to make, but I do feel I have made something that will make my life a little better. My hope is that it will make other people’s lives better and just perhaps stop people from needing air conditioning, and reduce carbon emissions just a little.

     Alistair  Just wondering if you have any progress updates on this project now that there have been a couple of summers to conduct some tests ?

    This is a really nice project!

    The concept it simple, but very useful. You described all the steps well, included all the pieces. I hope others will be able to make use of it.

    I've done this the old-school manual way for many years: check temperature inside and outside, and open the windows when it's cooler outside, close them when it's hotter outside. Laughing  But it depends on natural air movement, which isn't always available, and I don't trust the cats to stay safe... they tend to whack at insects on the window screens Laughing

    I might have to add this idea to my list of winter projects. I might have to add a smoke sensor to the outside sensor though Slight frown
