Radar is a valuable technology. Because of its unique features, it not only helped to win world war II. It also can solve many problems in our projects. Sensors included: RCWL-0516 (3GHz), HB100 (10GHz), CDM324 (24GHz), FM24-NP100 FMCW Radar (24GHz) I am a proud Patreon of https://www.youtube.com/channel/UC6mIxFTvXkWQVEHPsEdflzQ, https://www.youtube.com/channel/UCJ0-OtVpF0wOKEqT2Z1HEtA , https://www.youtube.com/channel/UCjiVhIvGmRZixSzupD0sS9Q , https://www.youtube.com/channel/UC2DjFE7Xf11URZqWBigcVOQ , and others. No Docker, No Microsoft Teams, Zoom 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 Links: RCWL-0516 (Presence): https://s.click.aliexpress.com/e/_9y4W4C or https://amzn.to/3d82zvG or https://bit.ly/31mvXsD HB100 (Speed): https://s.click.aliexpress.com/e/_ADfbUc or https://amzn.to/3d6Stem CDM324 (Speed): https://s.click.aliexpress.com/e/_AZNnGU or https://amzn.to/3vZuGWx FM24-NP100 24GHz (Distance): https://s.click.aliexpress.com/e/_AmT5cG Diagram RCWL-0516: https://www.snapeda.com/parts/rcwl-9196/RCWL/datasheet/ Info FM24-NP100: https://ebay.to/3swsfs4 Info speed sensors: https://bit.ly/3fhxFnd Info HB100 presence detector: https://bit.ly/31qcGXg ESP32 FFT sketch: https://github.com/G6EJD/ESP32-8266-Audio-Spectrum-Display The links above usually are affiliate links that support the channel (no additional cost for you).
