These are the questions answered in this video:
- Which Radar sensors exist, and how do they have to be connected to our boards?
- How do they compare?
- How can we use them in our projects?
- Which other technologies exist to solve similar problems?
- And finally, we should have a comparison chart, also including PIR and Lidars
