467 Radar Sensors from $3 to over $100: Which one is Best?

Great video. Thank you.
Do you think if it's possible to know how many people are detected?

Nice lessons teacher

Great video! why don't you do some GPR tests also?

I need one that can detect hypersonic missile.😂

You should get a 77ghz sensor off a wrecked vehicle and see if you can get data.

What good is a radar detector against lasers?

Andreas, thanks for the video. Since I'm in the Automotive ADAS field, what about using a front Adaptive Cruise Control Long Range Radar sensor ?

Swiss accent - well, the name says from somewhere about the middle of Europe. When hearing the your voice I first thought perhaps Scottish. No offence intended, never mind.
Schweizer Akzent - nun, der Name sagt von irgendwo etwa Mitteleuropa. Als ich Ihre Stimme hörte, dachte ich zuerst vielleicht Schottisch. Nehmen Sie es mir bittte nicht übel.

I love this channel so much

thinking to convert it to a GPR (Ground Penetrating Radar) but i think the diffculty would be getting a relable receiver, any idea?

Have you seen or read anything in the datasheets that suggest any of these can be used to passively work as a way of detecting the presence of similar radar signals being used?

We need radar for autonomous vehicles.

Great video. You mentioned the XM125 is a fast chip, but the data sheet only mentions 10hz. Is that considered fast in these low cost radar chips? Are there none closer to 100hz that can be used to measure higher order kinematics like acceleration/force/power?

How would one weatherproof one of these? I'd like to mount one outside... not sure what can be placed in front of the antennas and not affect performance.

Great video Andreas! One slight point I will make, the sensors can be powered by batteries, just for a shorter time period. I recently used the LD2410B connected to a 10,000 maH powerbank for all-day presence detection, it worked a treat. They are hungry little chips though!

I wonder what modules are used for radar speed control for cars. They seem to function for 50 to 75 metres.

I need one of those, good to make a turret )))

Am I greedy for being disappointed that none of these do phase array magic to produce an image? 🙈

That xm125 would be great for golf ball speeds. Aliexpress has a 60 Ghz ms72sf1 for 21 dollars and a command set up sheet page.

Thank You!!!! :)

Great video! 👍 Your can do improvment on your measurement methods. I saw that you got bad performance when you tested the Acconeer radar. In test range you had surrounded it with a metal bar close and a car at far range. It could create lots of clotter that the radar can hard to handle. See it as you turn on a lamp straight into a camera and then try see somthing. This is a natural limitation the radar has.
Try to have a similar enviroment when you the radars. You can add clotter as test of how the radar degraded. If you stand in front of a car you will probably be invisible. Continue your good work!

What's the cost of the guts of time-of-flight cameras nowadays?

Hello Andreas
Is there a way to contact you professionally for consulting on robotic sensing?

There are radar sensor module support external antenna

"Listen, man, I just need something good-enough to defend my home airspace with in pair with my cheap flak auto turrets."
"Ah, yes, sir, I believe we have something that would suit your needs. Follow me, please."

Silicon Radar gmbh makes some great products in this area

excellent as usual, Andreas. I have some of the tiny sensors I got from aliexpress without knowing in depth what the others did, but glad I got presence detection working and was so easy to setup. I didn't like that you have to get the extra wires in order to use them comfortably. but they are truly a nice piece of hw becoming available for so cheap. looking forward to the next videos on these topics

My biggest problem with PIR sensors is they will false trigger on temperature events (like the sun moving across my lawn). These would be great.

What I think would be extremely useful would be a sensor that had a wide but narrow detection pattern. I.e. I don't really need to be looking at the sky or ground. Just something that is focused more linearly.

Your accent is really terrible!

Very nice video Spiess! Would you recommend any of these sensors for water level measurement (since human body is just a bunch of water)? Thanks mate!

Sleep analyzing radars sound like an interesting topic! Looking forward to a video on that

I think it would be nice if you could use these sensors to take pictures of birds or insects when you think they are on front of your camera. Is it possible to detect something like a bee? When I did some experiments, I got lots of signals so I guess you need some built in cpu such that you don’t get false positives.

And by the way I'm spending five days a week 4 and a half hours a day and superintendents of German so that I can integrate here so I'm working on it but it's not going to happen overnight.

Can I buy radar sensor for vehicle without antenna and I design antenna for it

What behind the wall radar sensor do you recommend?

Danke für deine Arbeit an diesem Vergleich.

An excellent example of good technical content - presented succinctly and factually, and with a clear understanding of the audience needs.

Thank you Andreas for overview of currently available (cheap) radar sensors. I was looking for the application where radar sensor is used to measure the thickness of water film layer, needed for highway monitoring, to predict when aquaplaning could occur (with water film thicker than 0.7 mm). I need this for my lab experiments. The sensor should be buried in the asphalt, with teflon cover (something similar as IRS31Pro-UMB from LUFT, but in DIY version), and measuring range from 0.2 - 4 mm. Any suggestions?

Great!!

A while back, I did some pretty promising experiments using the RFBeam K-LD2 putting together a traffic counting monitor / data logger using this module together with a Pi PICO, an SD card slot module and some bits and bobs. It has onboard FFT, a serial interface and supports metering receiding and approaching targets simultaneously. The quality of readings were pretty good and within a plausible range of precision.

Hi Andreas,
i need a sensor to be swept over a field of aspergus, which has not yet come out of the groud, but locate it ...could you advice me?

Holderadiooooooo 🤪

awesome🔥

Hello Andreas, thanks for the great overview of radar sensors and your understandable and simple explanations about radar. We are a Swiss company what develops and manufactures radar sensors in the 24 and 60GHz range for various applications. Some of them already have signal processing on board and would fit perfectly into your test portfolio. If you are interested in an independent evaluation, we would be happy to provide you with evaluation kits.

Very useful! Thank you.

Hello Andreas. Thank you very much for the incredible overview about actual low cost radar sensors. You talk about FMCW sensors but beside this there is also the possibility to use FSK for distance measurement. There is a Swiss company what develops and sells different 24GHz and also 60GHz sensors including signal processing. The K-LD2 for example is a simple movement detector what can also measure the speed and direction of persons up to 15m. The K-LD7 uses in addition an FSK modulation and has 2 RX antennas what allows for an angle and distance output besides the speed and direction measurement. They also released a very small 60GHz FMCW distance sensor called V-LD1 what can be combined with a plastic lens to focus the beam. It has a very low power consumption and is perfect for IoT tank level gauging applications. I think these sensors could be a great addition to your presented overview.

Hi, I noticed that you didn't include the popular SEN0395 from dfrobot. Do you have a reason for this?

Think if your upstairs neighbours place one of these in every room to know where you are to listen to all your conversations.... 😮 which kind of countermeasure one can take to avoid this unpleasant problem?
