Amazing video! Just would like to add few observations I had while working with this sensor:
1. Yes, they work even when placed behind a plastic surface and even through thin concrete walls. Metal is the only enemy of the microwave sensor
2. The current consumption in idle state is higher for microwave sensor (approx. few milliAmps) when compared to PIR sensor (in range of few microAmps) so in case used in a battery powered product, PIR would take the front seat.
Apart from that it is definitely a pretty cool sensor and you seem to have covered all the essentials already!

Will it detect the small fan's rotation as motion? Fans which are inside the network switches?

[rupeshkoulge]

No microwave sensors do not work on SONAR, it works on Doppler effect which is totally different concept from Sonar which you mentioned. Sonar works on time of flight where as Doppler effect is change in frequencies which is used in radar. This sensor is not new, it's been in the market for couple of years now. Microwave sensors have their own disadvantages compared to PIR sensors so you need to explore a bit more and also mention them in your videos.

Really Amazing sensor I never knew about this before I had not used it. I have Used PIR Sensor. Now I will surely try with microwave motion sensor. Thanks a lot Sachin for this valued information

[signed]

WOW!!!, i am going to get these . Till now I thought that the pir sensor is the best, but now after watching your video microwave sensor is the best. Thank you very much

[erygion]

I'm getting one of these :) I've done lots of PIR but this is much better. Thank you for your time and work.

[atrumluminarium]

How are wifi signals when this is around? Does it interfere?

[keshavagrawal]

Hey dude! First thing thanks for sharing affirmative knowledge and your hardwork. Now try to make tracking face with microwave motion sensor and servo motor. this is something new in YouTube ! Try it if you can !

[CompanyBusinessCards]

Very interesting, but you forgot to show us the range of the microwave sensor

[rahulb]

Wow this is an amazing sensor for motion detection
In past i used pir sensor but i didn't calibrated it properly and i didn't get proper results
Sure i will use this for my upcoming projects

[muthumani]

I'm using this sensor for the past 2 years. Good one...

[sandipdas]

hey brother, i stay nearby rail station so, when trains passby objects in the house does vibrate little bit. what can i solve this ???? i wanna use microwave sensor but this problem wont let me do so 😅😅😅😅😅

[Yash_Tekale]

If i use pir sensor and replace in place of pir sensor is it work

[Khalsakilal]

Yes I have used both of them but some applications require line of sight motion detection where microwave sensor would be prone to unwanted triggers, as have installed IR motion sensor in my bathroom for light and exhaust fan.

[iamishu]

yes I was aware of this sensor I integrated this last year in my home automation

[innospire]

Thank you Sachin for this Super Valued Information. Keep posting informative videos like this.

We were planning to build a security device using Motion sensor but confused about the using of PIR or Microwave ( For there performance).

This video will surely help us to decide which sensor to use in our product.

Thank you..

[vedx]

Please make one video with Google assistant and microwave sensor.

[VijayAnand-dewu]

Brother you did it very well, but can we add this motion sensor to cadio

Just like even if sensor in active state but if we don't need any use of applience, we just turn it off by using Manual switch or from cadio mobile rather it will be in on state.
Is it possible

[matheokoning]

What is the quiescent current of this sensor?

[VinayakCB]

What's the effect of running Fan on this sensor ?
