Motion sensor that can "see" through glass

Motion sensor that can "see" through glass
From: Chris Schram <chrispam1@me.com>
I have grown more and more hard of hearing as I grow older. and I cannot
always hear when someone is at the front door. I'm looking for a motion
sensor that I can locate inside the front window.
I have played briefly with an old Radio Shack infrared motion alarm that
otherwise works fine, but can't "see" through glass at all.
I also have a little Wyze security camera that can detect motion, but it
seems way TOO sensitive to be useful.
Could ultrasonic be the way to go? That's a technology I've yet to play
with. It would be used in some sort of RasPi or Arduino configuration.

That might work, but it's a lot of hassle and complication. The doorbell
already is an electric signal. Could you not use that directly?

I did that. I bought a wireless doorbell with two "ringers"; one is in
the hall in conventional use, the other is hooked up to an old BeagleBoard
that had become spare. I found that the electronics could be powered
from 5 volts, available from the BB, so it didn't need plugging in to
the mains - fortunate, as the power supply is a non-isolated type.
I wrote some software to send a message to Pushover, which sends me an
alert on my mobile phone. It usually arrives within 2 seconds, but it
has to be admitted that occasionally it takes much longer, so it's
definitely not ideal.
The same idea can be used with a conventional doorbell. It's just a
case of appropriate interfacing.
As for why: in our house, if we're in the sun lounge, the ringer in
the hall is completely inaudible. Same applies if we're in the garden.
There are other places where we can be, and the sound of what we're
doing can drown the doorbell. So it's a different use case, but it
boils down to the same thing.
If anyone knows a way to get notifications to a mobile phone that are
always timely, I'd like to know.

I have purchased (through AliExpress) a number of RCWL0516 "Doppler Microwave"
motion sensors that provide (among other things) a single-bit binary interface
suitable for use with one of the Raspberry PI's digital pins.
As the device uses weak microwave radiation, it can sense motion through glass,
brick or drywall, and has an adjustable range of up to 5 metres (about 15 feet)
depending on the intervening media.
These devices typically cost less that $1.00 (excluding shipping).
Perhaps one of these would work for you.

Heh! You don't know about my doorbell. It's a brass replica of an
antique. You twist a knob on the outside of the door which spins a
clapper against the bell on the inside. No electronics, or even
electricity involved.

I'll explore that option then. Might be an amusing winter project. It
also occurs to me that there may be some Arduino peripherals that can
output some relatively loud noise. I may be able to forego the Pi
altogether. Thanks for the quick response.

Correct. In that case I modify my suggestion and suggest that a

is simpler and more relible than anything optical.

You might want to look into the doorbell units sold at this link.
https://www.amazon.com/Wireless-Doorbell-1PlusOne-Waterproof-Transmitter/dp/B07C
24N61X/ref=psdc_6291370011_t2_B08XYKY9R2
The claim you can purchase more receivers or units and using push-button
settings you can connect them all together and have the doorbell ring in
say 8 rooms or how ever many you combine together.
No, I have not used the product myself.

Look at Andreas "guy with the swiss accent" Spiess on youtube, he has videos on
various sensor types, including radar type, and connecting to rPi and
microcontrollers.
e.g. this playlist, but search his channel for more ...

Yes, I was going to say that microwave as opposed to infrared (PIR)
motion sensors work through doors, windows, etc.
Over here (UK) the DIY sheds have both PIR and microwave sensors available
quite cheaply.

Easy to set up initially but might be very hard (fft) if it has to
distinguish the bell from other sounds, if those are about the same level.
So I'd be inclined to fit a microswitch to the bell mechanism. Easy, direct
on/off signal but probably a little more finicky to set up.

I disagree about the reliability. Sound decays with the square root law.
If you place a microphone right nexr to the source it will be hard to
confuse it with an external equally strong signal anf if that happens it
should be obvious.
You can get a mechanical switch to be reliable for a long tinme, but
it's hard.
The suggested optical (or microwave) slution will be the least reliable
of all, I expect.

Assuming you already have a "push" doorbell on the outside, can you not
attach a lightbulb in parallel with the inside ringer?

Use a short range proximity photocell pointing at the clapper mechanism,
then an arduino to monitor *change* of state, so it doesn't matter if the mech
stops with the photocell obscured or not.
Something like this:
https://www.amazon.co.uk/Photocell-Infrared-Photoelectric-Proximity-Outside/dp/B
093HGNWT1/ref=sr_1_11?_encoding=UTF8&c=ts&keywords=Photoelectric+Sensors&qid=164
0358044&s=industrial&sr=1-11&ts_id=10256556031
Use two of the arduino outputs in antiphase at (say) 2kHz to directly drive a
ceramic sounder.
Done this sort of thing loads of times

Not really surprising -- it's one reason car and home interiors get
warm when the sun shines on glass. Ultraviolet light passes through glass,
gets absorbed by fabrics and what-have-you on the inside, and those items
then re-radiate the energy in the infrared band.

Sorry -- ultrasonic sensors will reflect off the window itself. You'll
pretty much have to fit the sensor (for almost anything except image
processing type detection [this image differs from last image]
outside the
window and run leads to the R-Pi (or whatever you use to process data).
A PIR sensor /might/ be usable in daylight (they are commonly used for
auto-activation motion detect security lights). They trigger on an IR
source moving between segments in the sensor window.

-work
Ultrasonic ("PING))" -- yes, the is part of the name for some)
sensors are more distance detection items than motion sensors, and may not
have a great range. Some old Polaroid cameras used them for focusing -- but
one has to account for the default focus being "infinity", and
depth-of-field on those being deep enough that anything around 15+ feet was
considered "infinity".

Ultrasonic wont see through glass or the clear lid of an electronic box,
(I did check to be sure). So it would need to be mounted externally, and
then you have the problem of weather proofing.

There are waterproof ones available, I bought one to use as a tank
water level sensor and the sensor is completely sealed up. Then again
the same applies to IR solutions, so one has to assume the OP just
doesn't like electronics outside.
I didn't see anyone mention mounting a laser pointing at a
slightly-angled mirror outside which reflects the beam back to a
light sensor. Just one more option, so long as it can be mounted
at a height where people won't accidentally look into it.

I've got a Raspberry Pi B with a Pi Camera mounted and use the 'motion'
package to record video when motion is detected - through a window.
Video is not very high quality, but you don't need that.
You could use inotify to watch the destination directory and email you
when motion is recorded.
