Project: Improving energy management in the home

Our idea helps people use renewable energy to power home appliances more effectively. Renewable energy from the sun and wind are not always reliable, so we wanted to create a system that shows when a lot of renewable energy is likely being produced. We realised that, in the UK, the Met Office produces weather forecasts that we can use to plot how much energy solar and wind farms are likely to produce. We got the Met Office data using an API on a Raspberry Pi, then converted it to numbers before multiplying them by conversion factors and adding them together to get a total amount of energy available. We presented this information in a graph, so it is simple to understand.

We also added a second part to our programme that uses live local data. We used an enviro+ sensor that measures changes in pressure and light caused by wind and the sun. We convert this live data into power and if there is enough energy then an LED lights up and a message is displayed. If you press the button on the screen, an email is sent to tell you that there is renewable power available.

Our aim would be to use this information to control appliances remotely using the Internet of Things.
