Bodo MenkeI am done with PIR. Radar is so much (!!) better!After struggling with my Zigbee-based Passive Infrared sensors (PIR), I decided to move my 2 yrs proof of concept with radar-based presence detection into production. It is like a time-warp! Monitoring a 60sqm area with only one (!) sensor and a precision of centimeters! It is a blast for adaptive lighting. Light follows movement! So much creativity. So much fun! 🤩 <a href="https://hessen.social/tags/PIR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PIR</a> <a href="https://hessen.social/tags/Radar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Radar</a> <a href="https://hessen.social/tags/mmWave" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mmWave</a> <a href="https://hessen.social/tags/FMCW" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FMCW</a> <a href="https://hessen.social/tags/UWB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#UWB</a> <a href="https://hessen.social/tags/PresenceDetection" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PresenceDetection</a> <a href="https://hessen.social/tags/HomeAssistant" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HomeAssistant</a>… (1/4)

Bodo MenkeWhy did I decide to ditch traditional PIR movement detection and move to 60 GHz radar-based presence detection? Because battery-powered PIR are pain in the ass. I tried various zWave and Zigbee devices over a time-span of 10 yrs. They all suck - earlier or later.

Bodo MenkeInterested in radar and what it can do for you? Here is a nice overview from an automotive perspective on what FMCW can do vs UWB. FYI: UWB, used in iPhone since a while for precision finding, is a similar technology, but with a lower frequency. <a href="https://hessen.social/tags/PIR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PIR</a> <a href="https://hessen.social/tags/Radar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Radar</a> <a href="https://hessen.social/tags/mmWave" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mmWave</a> <a href="https://hessen.social/tags/FMCW" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FMCW</a> <a href="https://hessen.social/tags/UWB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#UWB</a> <a href="https://hessen.social/tags/PresenceDetection" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PresenceDetection</a> <a href="https://hessen.social/tags/HomeAssistant" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HomeAssistant</a> <a href="https://www.novelic.com/blog/60-ghz-fmcw-radar-vs-uwb-for-in-cabin-monitoring/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.novelic.com/blog/60-ghz-fmcw-radar-vs-uwb-for-in-cabin-monitoring/</a> (2/4)
