Day 2 Presentation

So, we called our home “GreenGuard”. It is a sustainable IoT-based smart home solution designed to enhance energy efficiency, comfort, and safety. It integrates multiple sensors and smart components to intelligently manage home environments while minimizing energy consumption. The key features include:

🌡️ Smart Climate Control:

Automatically opens windows when the temperature exceeds 20°C or humidity surpasses 70%, promoting natural ventilation.

Fan activation within a comfortable temperature range (20-30°C) to improve air circulation without overcooling.

🔕 Silent Mode with RFID:

Mutes alerts using an RFID card, reducing noise pollution and conserving power when not needed. (we are still trying to get the RFID tag reading to work)

🚪 Motion-Activated Door Control:

Opens the door only when motion is detected and a button is pressed, enhancing security and minimizing unnecessary power usage.

🌐 Real-Time Weather Integration:

Displays next-day weather forecasts on the LCD, optimizing heating and cooling decisions based on external conditions (requires WiFi).

🌱 Energy-Saving and Eco Modes:

Window and fan behavior adapt based on indoor conditions, reducing HVAC system reliance and lowering overall power consumption.

📊 Comprehensive Status Monitoring:

Real-time temperature, humidity, and air quality data displayed on a 16×2 LCD for continuous home status awareness.

Day 2 Presentation

Home that tracks electricity prices and adapts to it

Day 1: We gathered our team members according to our interests and built our smart home. Then we tested a few existing codes. We brainstormed with each other and finally agreed about the main points that we are all going to build for our sustainable home. We might not be able to implement everything, of course, but then these could remain as future scope.

We finalized our presentation before leaving so that we can think more about the solution implementation at home.

Day 2: Immediately after presenting our solution, we received valuable feedback that will help us proceed.

- We started by thinking about a good way to fetch the real-time data from URLs (electricity providers and/or weather forecast sites). We are thinking if we should fetch the data every hour or what would be the good interval to get the updates.

The battery usage of the IoT devices has to be taken into account. We then decided to get the data immediately when the device is turned on and then we hard-code the moment/timestamp during the day (at midnight for instance) when it updates the prices/timing, etc.

- For now, we are looking for wifi connection, but then for the sake of the simulation and demo, we will show the fluctuation of prices in a loop like

- 11:00, we already managed to get the connection working and read some prices.

- Audio alerts are working, and we are thinking of having different alerts for different functions. In addition to audio alerts, we will have the LCD showing about the price and weather. For accessibility reasons, we were thinking about impaired people that have trouble seeing/reading; they will have “Morse code”-like“ alerts to be able to understand the meaning of the beeping.

- After discussion, we decided to use the left button to turn off the buzzer and the right button to switch between the data that is shown in owr LCD. For instance, it shows the electricity price and the temperature.

- The LED turns on when the prices are low for example. So, we are fetching online the electricity price from the electricity provider (it could be for example extracted from here: https://vare.fi/sahkon-hinta/sahkon-hinta-nyt/?utm_term=s%C3%A4hk%C3%B6n%20hinta%20nyt%20p%C3%B6rssis%C3%A4hk%C3%B6&utm_campaign=SEM+%7C%C2%A0S%C3%A4hk%C3%B6n+hinta&utm_source=adwords&utm_medium=ppc&hsa_acc=9613272229&hsa_cam=21500165233&hsa_grp=164788003843&hsa_ad=706690047770&hsa_src=g&hsa_tgt=kwd-2366899273632&hsa_kw=s%C3%A4hk%C3%B6n%20hinta%20nyt%20p%C3%B6rssis%C3%A4hk%C3%B6&hsa_mt=b&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=21500165233&gbraid=0AAAAAC5G_NIUGrEO4FEF5yBbn5WpWL1ER&gclid=CjwKCAjw_pDBBhBMEiwAmY02NgOSaQ7zkck59UzrX335iREoeV3npKda0DlU1P5GvDATViJVcy2K7xoCwXgQAvD_BwE )

And according to the prices, our home appliances are used. The current price is also displayed on our LCD and the right button gives us the option to switch to other views. If the price is high, the buzzer goes on and the red light is on. The buzzer could be turned off with the left button. We could add a green led light all the time when the price is considered low or negative
