Hey STEMologists! Have you accepted the Re-set the ‘stat Mission? It’s all about fighting climate change by adjusting the temperature of your home, and a great tool that can help you do this is a smart thermostat.

It’s just one of the many smart devices that makes our lives easier, but have you ever wondered what makes them so smart? Keep reading and find out!

The Internet of Things

You know how you use the internet to look stuff up and chat with your friends? Smart devices use the internet too! Things like appliances, cars, and yes, even thermostats, can use the Internet of Things (or IoT for short) to receive and exchange information.

Here’s how it works:Each device that is connected to the internet makes up the IoT. They share information through something called the cloud – no, not the ones in the sky, but the technology cloud.




The technology cloud lets devices and computers that are really far away from each other connect and share information. It is a network of different systems that stores data like photos, videos and other information (cloud storage), allows you to make updates to that data (cloud services) and has really powerful computers that run apps and websites (cloud servers).

Through the cloud, you can control your smart devices and access their data from anywhere just by opening an app on your tablet or phone.

What can smart devices do?

Thanks to the IoT and the cloud, we can now access all sorts of new data from technology and devices that have been around forever. Now, we have…

• thermostats that know the current temperature of your home
• watches that can read a heart rate and/or body temperature
• weather devices that read wind speeds and humidity
• tools used during surgery to guide surgeons
• sensors on a car that can detect potential collisions

How does a smart thermostat help you save energy?

First, you need to know what a thermostat does: it lets you control the temperature of your home. If you’re too cold or too warm, just adjust the thermostat and you’ll be comfy in no time, but be careful about how much you adjust it because heating and cooling your home uses a lot of energy.

Your parents could adjust the thermostat from their phone so it wouldn’t have to work as hard to keep your house warm or cool from 8AM to 4PM, allowing you to save energy. Some smart thermostats can even ‘learn’ when you’re home or away and adjust the temperature on their own. If you’ve shared your phone’s location, your smart thermostat can even warm or cool the house as you get closer to home.

We think the technology that makes these devices so smart deserves an A+!

Smart Device Fast Facts

• Smart devices are ‘things’ that are connected to other ‘things’ through the internet. Together, they make up the Internet of Things (or IoT for short).
• Smart devices share and store information (data) using the cloud (the technology cloud, not the white fluffy things in the sky).
• You can control your smart devices using apps on your tablet or cell phone (which are also smart devices)
