When my late father moved into the nursing home they stuck him in the basement which had long hallways and at the time was mostly vacant. He had a walker and it didn&#x27;t dawn on us it would ever be a problem.<p>But then he had a fall and couldn&#x27;t get up. Anywhere else in the facility a staff member would have found him within five minutes. After a half hour and multiple failed attempts to stand he remembered his cell phone and called a Lodge member who took another twenty minutes to get there and help him up.<p>He didn&#x27;t call me because he didn&#x27;t want me to know he fell. But his Lodge buddy ratted him out to me and I was able to get him on a list for the first available room upstairs. A device like this could have alerted someone at the facility that he had fallen, this is a very big deal and it&#x27;s going to save lives.

So I love Seeedstudio and their innovative and affordable hardware. I bought quite a lot over the past years and always been quite happy for the quality.<p>However, they blame the chip shortage for their own inability to manage their inventory.<p>I&#x27;ve had to cancel my last order (all items in stock and paid for at the time). I contacted them after a few weeks seeing the items were not yet shipped. They replied that some items were out of stock. I agreed to remove them. A couple of days later, they reply again that more items (similar sensor as the one featured here) are no longer in stock....<p>This tells me that that their website isn&#x27;t showing the actual stock status at the time of order, that their system doesn&#x27;t reserve quantities for items already purchased, and that they don&#x27;t really communicate unless you chase them (but they respond quickly).<p>If you purchase anything, have a follow-up ticket within 3 days to make sure they take care of your order and quickly assert whether all parts are available.<p>I like Seedstudio but they need to sort out their logistics and inventory management. My previous order took 4 months to ship and had multiple shortages and delays as well.

Anyone remember how viral &quot;I&#x27;ve fallen and I can&#x27;t get up&quot; went? This was apparently the main use case and selling point for those devices back then, and it still is now.

The breath rate application really got my mind turning here— replacing 2 wearables (breath monitor, fall monitor) with a wireless device, and pulse sensing can already be done by video. Imagine walking into a hospital room or grandma’s home &amp; having full bio monitoring with no tubes or cables…

That board shouldn’t have passed QC? The largest SMD on the first image of the board is severely off-centre.

&gt; what it sees is not personally identifiable<p>This is ridiculously naïve. Gait recognition is a thing. Who knows what other kind of analysis can be done using point cloud and velocity vectors.

This ought to make for inexpensive home automation sensors that do much better occupancy detection for rooms than pIR sensors, which stall out if you&#x27;re sitting and don&#x27;t move enough to trigger &quot;motion&quot; but still want lights on in the room.

I like fall detection topic. It has purpose helping elders, albeit it will probably not be another hockey stick growth venture. I invested some time and conducted interviews with potential customers. For the sensor comes time of flight camera <a href="https:&#x2F;&#x2F;www.seeedstudio.com&#x2F;DepthEye-S2-VGA-Resolution-ToF-Camera-p-5095.html" rel="nofollow">https:&#x2F;&#x2F;www.seeedstudio.com&#x2F;DepthEye-S2-VGA-Resolution-ToF-C...</a> in mind. It can be used for other applications in care too. Care homes have €€€ and would like to start test projects immediately. Maybe somebody wants team up on this? My e-Mail is in my profile.

Im extremely interested in how well this breathing rate detection works. Im currently working on an optical respiratory rate monitor project.

Woah, I didn&#x27;t notice til reading a comment further down that this thing is mounted on the ceiling, so it notices remotely that a person has fallen. I thought that the person had to wear it, which is a nuisance. Ok, I want to set one of these up for an elderly family member. Way cool, wow.

&gt; With the enhanced Infineon Doppler radar and the standard algorithm, the module is an ideal solution for individual applications like elderly health care, smart home, and danger alarm.<p>Anybody know what they mean by &quot;the standard algorithm&quot; for fall detection?

Wow. Amazing technology.<p>I would buy the &quot;Human Static Presence Module&quot; in a second if there was a tutorial on how to set it up (code wise). The YT video linked on the page made me way more curious then I thought I&#x27;d be.

500mw power consumption. That&#x27;s quite a bit.

Wouldn&#x27;t an accelerometer be more suited for fall detection?
