Todays irrigation and garden watering techniques rely on sprinklers operated on a timed schedule. Due to rain, moisture content Of soil may vary and isn’t uniform everywhere. With a swarm Of soil rovers, we can analyze moisture content quickly so that appropriate distribution of water (irrigation) can be applied. Advantages: Reduction in wastage of water, Better yield of crops, No damp gardens. Idea description: Todays irrigation and garden watering techniques rely on sprinklers operated on a timed schedule.

Especially in big Cities like Stuttgart, particulate matter emissions due to poor traffic flow impose a serious threat to public health. Our approach tackles this challenge by enabling decentralized Car-2-X communication, today! We’ve built a universal IOT-upgrade for light signals to provide real-time information to car drivers. As each individual will be able to optimize their driving behavior, emissions and fuel consumption will be reduced.
