All 18 projects are listed in the order they were submitted to the Hackathon. Positions in this list are not related to the winners selected by the Jury

IoTraffic

Utilizes IA to recognize cars from camera (ESP32Cam) images and stores the data on the Tangle. Regulates traffic lights timing according to the amount of cars. Perform actions such as call an ambulance if it detects accidents. Detects cars speed and can post a photo of the car together with its speed on the Tangle.

IOTA Pet Feeder (Vending Machine)

IOTA based Street Pet Food vending machine allowing to release food and water when an IOTA payment is received. The PoC is built with . Flow: you pay iotas to the feeder address, the iota_check_balance.py script gets the updated balance and sends that data to Tangle, the feeder will read that json data from tangle (IOTA Streams) with the updated balance and then drop the food and water. The machine prototype is built with paperboard but the project includes plans to 3D print a production ready casing.

Ayni (Smart Agriculture)

Hydroponic Irrigation Control System developed to ease the access of small farmers to edge technology. It allows us to sense, monitor, present and label Soil Humidity, Air Humidity, Pressure and Temperature data to control a water pump according to these values. Sends sensors data to the Tangle via Streams and also provides visualization through Grafana.

Argos Delivery (Supply Chain Tracking)

Delivery Tracking using Digital Twins on the Tangle (Streams). Sensors attached to the package send their current state to the Tangle, the Argos backend fetches that data, applies business logic to it and thereby determines the state of the delivery. In the case of a package drop, the Argos frontend allows to see where and when the drop has happened. It includes QR generation and scanning to tag packages sent.

IoT Licence Plate (Smart Parking)

The project establishes an infrastructure that must be installed in a car park. It is composed of sensors that detect the presence of parked cars, it also offers the user an app with which they will have the possibility of paying for their parking with IOTA and setting various configurations of parking times. The sensors and the IOTA protocol allow to automate the entire process. All this user parking information is sent to the Tangle through Streams
