[@JoseEduardo-dg2ki]

Thanks for exposing me to this. That's almost magical hardware. Great video and humour!

[@Mellow_labs]

Glad you enjoyed it!

[@ElakitheLion]

Your videos are making me want to set up home automation more and more. I'd been lookin at air quality sensors, but adding that millimeter wave sensor would be so useful too!

[@collie147]

Love the sexy soldering!

[@cooperised]

The PIR on the EP1 is great for avoiding false positives on the mmwave in larger rooms. PIR to turn the lights on, mmwave to turn them off, perfection. Oh and the DFRobot sensor in the EP1 doesn't support zones, but I guess you found that out by now 😁

[@Mellow_labs]

Yeah also don't have the mounted up high, It won't recognise short people.

[@julianbowen7112]

i need to have a play with one of these presence sensors. human proximity detection fitted into a droid to trigger animation sequences would give a nice illusion of ai

[@andy_warb]

Nice! I got an EP1 this month and it’s pretty awesome! I built a self-built one using a Seeed Studio MMWave sensor in a 3d printed Gonk from starwars! He lives in my kids room and turns off the lights when nobody is around because he’s got all the govee unicorn vomit and always forgets to turn it off!

[@weirdsciencetv4999]

As a parent of young children (and a maker), I like this "ability to sense breathing". It means I can get an alert if my child stops breathing for instance, or has difficulty.

[@meeskees702]

Well no, not like that. It is able to sense breathing, but not exclusively breathing. Any movement will do so it’s not of much use for this purpose.

[@andy_warb]

Do you know where we can buy the Asian guy?

60GHz sensors can tell heart rate, distance, do fall detection, etc... normal mmwave ones are 24ghz (if they're good, if they're less than 24ghz, don't touch 'em)

[@gearscodeandfire]

Impressive response time!

[@hoteny]

1:21 imagine a horror movie where there is a counter which shows 3 but only you were in the zone

[@germanobressani]

nice

[@danielbocelli]

Sooo cool and inspiring 🏳️‍🌈

[@psikeyhackr6914]

They need that in Japan where people die alone in apartments and are not fpund for 3 weeks or more. So if there is no motion in the bathroom or kitchen for 3 days energency services is notified. Good for people over 60.

[@Ernzt8]

Nice project and the coding installation looks very simple. An almost unrelated question: what gauche of wiring did you use inside the box?

[@Mellow_labs]

its 28awg Silicone Electrical wire, I actually went over how much I like it in a previous video.

[@Ernzt8]

@@Mellow_labs I must have must that. Thanks :)

[@valzzu]

dis i must do maybe. i'm bit jealous of u getting free parts

[@lezbriddon]

2 things that confuse my sensors, cats and big moths....

[@RubenKelevra]

Get some smart light bulbs from Lidl. The color ones are like 10 bucks if you get the 3 pack :)

[@wagnerfontes2]

I would be interested in seeing the configuration of zones and multiple people detection. Maybe an idea for a next video?

[@Mellow_labs]

Sadly I learned after the fact that these particular mmWave sensors don’t do zones.

[@davetreadwell]

I bought an EP Lite... its an absolute PIG to set up on home assistant for setting zones etc

[@MrZanyZain]

Have we gotten a partner reveal!

[@Mellow_labs]

My partner prefers not to be in the videos but they show up on my instagram from time to time 😅

[@Geeksmithing]

Um. You misspelled "presence" in the thumbnail my friend! Awesome project as always!

[@Mellow_labs]

There are 3 versions of the thumbnail, maybe you just got the one with the intentional misspelling 😂😂

[@Geeksmithing]

@@Mellow_labs u GOT ME!!!!

[@johnlandgrave1617]

Will you share your case stl files on Printables?

[@Mellow_labs]

I would but I don’t actually recommend it, it’s made to be up high. Which I now know is not where you want to put a mmwave, it’s not very good at detecting shorter people. So you’re better off putting it about knee high.

[@ferdm9646]

A simple IR sensor cant do the same? or what's the rocket science behind this ?

[@Mellow_labs]

In most cases where I’ve tried IR sensors, they suck. A little bit of sunlight through the window is going to trigger them constantly. Also they don’t have the range of a mmwave sensor, this one can detect you from 24 m away.

[@jackipiegg]

9:15 Why can't this be used like those that uses coin batteries? e.g. aqara sensor That wire will definitely not pass spouse approval.

[@Mellow_labs]

The reason this DIY setup can't use a coin battery like some other sensors is due to higher power consumption. Beetle ESP32-C3: ~160 mA at 3.3V mmWave Sensor: ~3.5 mA at 3.3V BME680 Sensor: ~3.1 mA at 3.3V Total Power Consumption: ~165 mA A CR2032 coin battery (220 mAh) would only last about 1.2 hours with this setup. The Aqara Presence Sensor, also uses a wire due to similar power needs. Despite initial concerns my partner, quickly appreciate the functionality and benefits of this sensor.

[@SirTodd.]

why spell it "waching machine..."?

[@Mellow_labs]

I’m have dyslexia

[@SirTodd.]

oh ok. I figured there was a legit reason. didn't mean anything by asking, thanks for the time and answer. great video too btw
