Inspiration
In Eton College, heating contributes to 70% of all CO2 emissions, despite only being turned on for two terms each year. It also costs £2 million to run every year, and £1.1 million just in the Michaelmas half. Most of the time, students tend to leave their radiators running on max settings throughout the day and night; this not only makes their rooms too warm, it also wastes a significant amount of energy which can easily be saved. We’ve built a device which addresses this problem by automatically changing the temperature of a radiator.
What it does
The user enters their details and their preferred room temperature into a website, which sends the data to the device. The device then adjusts the radiator based on the user’s target temperature.
How we built it
We used a Raspberry Pi Pico for the microcomputer, and we 3D-printed the box and clamp to fix the device onto the radiator knob. For the software, we used React Native for the front-end UI, and Express.js and MongoDB for the backend and database.
Challenges we ran into
We had some difficulty in designing the CAD model of our device, as well as 3D printing and assembling the different parts.
Accomplishments that we're proud of
We learnt how to design CAD models using Fusion 360, which is a very useful skill in engineering.
