You may be listening to much more about Millimeter-wave sensors – this is what it’s essential know
Millimeter-wave (mmWave) expertise is quickly gaining traction within the sensible house market, which isn’t stunning because it provides a variety of advantages over conventional movement sensors.
In case you’ve been maintaining with the sensible house information over the previous couple of years then you definitely’ll have heard concerning the likes of Meross and Aqara launching sensible sensors, and it’s additionally more likely to be the sensible sensing tech that Samsung has been waxing lyrical about with reference to the brand new SmartThings House AI platform.
However, even then, you’d nonetheless be forgiven – until you’re {an electrical} engineer with a ardour for top frequencies within the electromagnetic spectrum – for not likely figuring out precisely what mmWave is, and the way it’s set to vary the sensible house within the very close to future.
However concern not as this information offers you an honest overview – with out getting too slowed down within the science – of what mmWave is, its benefits, and the way we’re more likely to see model’s utilizing it for revolutionary, futuristic, sensible house options.
What’s mmWave Expertise?
Millimeter-wave (mmWave) operates within the Extraordinarily excessive frequency (EHF) space, as outlined by the Worldwide Telecommunication Union, and encompasses the vary of radio frequencies from 30 to 300GHz.
This implies it falls inside the microwave portion of the electromagnetic spectrum, plonked between tremendous excessive frequency (SHF) and the terahertz band.
It’s mostly used, previously few years a minimum of, for the 5G mobile community because it provides each excessive speeds and elevated bandwidths, making it a really perfect for what our media-intensive, speed-hungry smartphones want.
By way of the sensible house although, we’re seeing mmWave radar tech utilizing these radio waves to detect movement and, extra precisely, presence.
This expertise is very delicate and may detect even the slightest actions, making it best for quite a lot of sensible house functions.

How does mmWave sensing work?
In contrast to conventional movement sensors, resembling PIR motion sensors, the brand new arrivals within the mmWave sensor market don’t simply search for a primary movement to kick-start an automation, they’re able to detecting even refined actions, resembling respiratory, making them extra dependable than conventional movement sensors; and that’s why they’re typically known as presence sensors, fairly than movement sensors.
Take Aqara’s flagship FP2 sensor, for instance. It’s able to, utilizing a single mmWave radar sensor, of monitoring rooms as much as 430 sq. toes.
Nevertheless it’s not only a larger space for movement detection. In that room you possibly can create as much as 30 zones and arrange particular person automations for every zone. And it will possibly do all this for as much as 5 folks at a time. This implies which you can get tremendous detailed with reference to what types of motion set off what actions.
You possibly can have an automation, subsequently, the place somebody sits on a settee within the night and a TV-time routine kicks in – assume lights dimmed, Netflix on, 5.1 system powered up – whereas on the similar time having it activate the lights within the kitchen, and switch the heating on in that room, if somebody approaches the kitchen door.
You possibly can then have it in order the TV and the AV system energy down if it detects you’ve gotten fallen asleep on the couch.
I’ve been utilizing an Aqara FP2 in my backyard workplace for some time now, and I’ve it configured to do a bunch of various stuff, relying on the place I’m within the room, and at what time.
For instance, if I sit at my desk within the morning it’ll activate my pc and inform my sensible speaker to play my favourite morning radio station (KEXP, in case you care).
If I’m nonetheless at my desk typing away after sunset, it’ll flip some lights on, but when I sit on the couch after darkish, it’ll hearth up my Fireplace TV.
Your routines and automations are solely restricted by your personal creativeness. Manufacturers like Aqara do supply some recommendations although, constructing automations resembling fall detection instantly into its units and accompanying apps.
Samsung needs to take issues additional although, with the newly introduced SmartThings House AI, which goals to create a better, extra intuitive house that adapts to your life-style with little or no effort in your half.
The large thought is that your sensible house will be just right for you, within the background, utilizing sensors in on a regular basis units – assume TVs, audio system and kitchen home equipment – with out you even needing to know that they’re there.
The perfect mmWave sensors

As talked about, Aqara is already within the mmWave recreation and really has a trio of mmWave sensors available on the market.
The primary one to land, the FP2, remains to be the highest canine regardless of being launched in again in 2023. For a wise sensor it’s on the pricey-side although, at $80.
And that’s the place the FP1E sensor got here in; it’s a slimmed down model of the FP2, nonetheless boasting mmWave tech however at a sub-$50 price-tag.
A 3rd mmWave presence sensor from Aqara, the Presence Multi-Sensor FP300 (pictured above) was revealed at CES 2025 and, not like the FP2 and FP1E, it’s battery powered and doesn’t must be plugged in.
Aqara’s rival Meross has additionally launched the MS600, boasting mmWave, and was described by its makers as “the primary Matter-compatible presence sensor.”
That assertion rings true because the Aqara’s presence sensors aren’t native Matter system; they reside in an Aqara sensible house system and want a local hub to function.
The LifeSmart mmWave Human Presence Sensor really launched earlier than all of those, and goes within the ceiling like a kitchen/lavatory highlight and, when you store round on the same old Chinese language electronics shops, you’ll additionally discover a bunch of lookalikes to this, all seemingly suitable with the Tuya sensible house system.
Nevertheless, for now, I’d suggest sticking with Aqara or Meross however the checklist of manufacturers within the mmWave house will certainly broaden quickly within the subsequent 12 months or so.
FAQs
Whereas mmWave sensors supply important benefits, conventional movement sensors like PIR sensors are nonetheless cost-effective and appropriate for a lot of functions. It’s seemingly that each applied sciences will proceed to coexist within the sensible house market.
Manufacturers like Aqara and Meross supply a variety of mmWave sensors. Keep in mind that mmWave sensors could be costlier than conventional movement sensors.
Like all linked tech, mmWave presence sensors can work with Alexa or HomeKit, however it relies on the particular mannequin and your setup. Aqara and Meross’ mmWave sensors work with a variety of sensible house methods.
