I live unfortunately in a area where 24GHz is unlegal so I need to go with 60GHz, so that’s I find Seeeds mmWave sensors are interesting
Yah. Thanks. I got Crlogic’s code working on your previous sketch. Will the same snippet work with the new updated code? I will try today. Thanks for the reply.
Yep it should be fine
Very nice list you have compiled. Thank you for your contributions to this thread.
Allow me to add a few more to your list: millimeter wave Doppler radar ,Biological Radar Sensor,microwave radar sensor_Good Display
They have a “Wireless 60G Radar Module for Human Movement Tracking, IR60TR1A” which looks interesting.
Seems like Seeed is branding and re-selling perhaps the same exact sensors as in the link you posted.
Nice theory. And it would not surprise me in the slightest if it turned out to be true.

Could you share your code please?
Don’t look at me, @phillip1 is the mastermind here! I am only 4 hours into a 31hr video of learning c++ on YouTube, ha! Watching on 2x speed is trippy.
Everything is posted above.
I made it 5 hours into the video 
Actually, that’s just the manual. I’m trying to get mine going today and the actual device is labelled “+ 12V -” across the top of the terminals. mine also came with an adaptor but I threw that in the bin (not AU certified).
@ferbulous , did you only end up using the wifi one then? Haven’t got another zigbee version? I paired my zigbee sensor with ZHA but I’m not getting a binary sensor or anything to show presence in HA…
I did get the zigbee version, using z2m
Seems to have the same limitation with aqara fp1 & dfrobot i.e detects ceiling fan movement which gives off false human presence detection
I’m gonna try some diy solution using tinfoil if it could prevent detecting the fans. Seems to work for the fp1
I might need to test the wifi version again
Ok thanks. I may have to move from ZHA to Z2M…
I have a couple of these sitting on my desk, but haven’t had time to play with them yet.
I implemented 3 of the dfrobots SEN0395, and they are working pretty well. Got the MR60FDA1 to see the difference between the dfrobot 24GHz and a 60GHz sensor.
In my use cases I don’t care at all about how quickly it goes back to off - the fraction of a penny it costs to leave LED lights on for an extra 10 minutes is meaningless versus the lights turning off when they shouldn’t. That just isn’t money I want to chase - in fact the LED bulbs dying sooner from extra on/off cycles will likely cost more than the savings from a couple extra minutes here and there over the lifespan of the bulb.
I am more interested in better presence detection when people are present and stationary (reading for example). PIR is horrible for that use case.

I’d be interested in such a thing.
Now that I have the 60GHz sensors up and talking in arduino ide, I’ll circle back and try try your ESPhome code on them.
Seems fairly straight forward.
Right now what I see in arduino logging (based on the goofy library seeeduino provides):
19:37:36.774 -> ----------------------------
19:37:36.774 -> 53 59 80 2 0 1 0 2F 54 43
19:37:36.774 -> Radar detects None.
19:37:36.774 -> ----------------------------
19:37:49.412 -> 53 59 80 1 0 1 1 2F 54 43
19:37:49.412 -> Radar detects somebody.
19:37:49.412 -> ----------------------------
19:37:51.039 -> 53 59 80 2 0 1 2 31 54 43
19:37:51.039 -> Radar detects somebody in motion.
19:37:51.039 -> ----------------------------
20:53:07.371 -> 53 59 80 2 0 1 1 30 54 43
20:53:07.371 -> Radar detects somebody stationary.
20:53:07.371 -> ----------------------------

Sweet! How are you finding them when it comes to detection sensitivity, on to off time and interference from other objects?
My initial thoughts -
It is extremely sensitive. Probably not going to be usable for those with pets… But I could be wrong, maybe it needs some more setting tweaks (I’ve only started playing with it).
Seemed to go ‘off’ pretty fast, once it decides there is no person/motion. Although I didn’t pay that much attention to that, as I don’t care much about off speed.

Hi, do ceiling/stand fans get detected by the 60ghz version like with the dfrobot?
I have some sample code posted somewhere in this thread for writing sensitivity settings and whatnot.
The thing about it turning off fairly quickly is actually quite good news. That was the issue about the 24ghz one
Has anyone experimented with the point cloud data? Just considering getting hold of one of the 60GHz Seeed fall detector sensors to play around with, and if the point cloud works well it could solve a lot of problems for me - I could just read the point cloud data and post-process (probably in Node RED) to see if the detected points lie within a bounding box. I’m thinking I could create “dead zones” that way, particularly through doorways for more accurate room presence detection, or below knee-level as a cat filter. Depends on how accurate the data is though.
