Consider the following scenario: Sarah is getting ready to leave for work. She often forgets her phone and keys at home, which causes delays and frustration. She wants a reliable solution to ensure she never forgets these essential items again.

In this light, the product "Doora" might help. Using Doora, the solution is farirly simple: Sarah attaches RFID tags to her phone and keys and registers them in the Doora companion app. She sets up an ‘Always Necessary’ item category for these items. As Sarah approaches the door, Doora scans for the RFID tags. If the phone or keys are missing, Doora sounds an alarm, alerting Sarah to retrieve the missing items before leaving. 

Technically, the project depends on an IoT Device using an ultra high frequency RFID scanner conntected a raspberry pi and a magnetic door switch atttached to the door.

There are around 34 million pets in Germany, including around 15 million cats. The four-legged friends are popular pets, but their lifestyle can ruin the owner's sleep. Anti-Scratch was developed to prevent this problem. The device is small and can be placed anywhere in the house. The setup is done in three steps; attach the device and connect it to power, connect it to the home WLAN and set the times when the device should be active. A motion sensor detects movement even in the dark and deters the cat using ultrasound, flashing light and insect-like sounds. These effects are loud enough to make the cat think twice about scratching the door, but not loud enough to wake a human. Thus, a peaceful coexistence between humans and animals can be restored.

Plant owners often encounter the distressing issue of their indoor and outdoor plants wilting and dying, particularly when they are away for an extended duration like vacations or business trips. 
Such challenges can discourage people from engaging in urban gardening altogether. GreenGuardian addresses this issue by utilising humidity/moisture sensors, electromagnetic valves, and a 
microcontroller to constantly monitor the moisture levels in the soil. The user is able to calibrate his desired moisture level through a web interface. For this the system uses the individually recorded moisture which allows the system to extend to any type of plant, soil, climate or otherwise variable environmental factor. Futhermore, GreenGuardian gives insight to the plant's vitality through a real-time graph displaying the plant's moisture level and the configured threshold.
