#67215 Radar update:

Slid the radar module into some heatshrink sleeve, powered everything from a usb powerbank, and tried a few sensitivity tests... it still senses reliably up to 5 or 7 meters away even through the sleeving.

Sat it on my campers dashboard, and it reliably detected movement through the triplex glass windscreen 1 to 2 meters outside the vehicle.
That's quite a significant result, because it means that sensors could be placed inside vehicle windows to provide perimeter approach alerts if wished.

Similarly for household use, because it worked from behind wood panel doors, under tables, under counter-tops, and behind glass windows.

Module alert timeout is 2 seconds - continued retriggering extends the original alert until 2 seconds of inactivity timeout. The timeout could be changed by changing a surface mount capacitor, but it would be easier done with software in Esp-Basic.

#67268 Radar Update 2:

This might knock yer socks off...

Used the previous test program and power bank as seen in 1st vid: https://youtu.be/M8avhsgDqcM

Taped the radar module onto the LNB of an old satellite dish shown in 2nd vid: https://youtu.be/M_5O80m3qmU

Did a range test... WOW ... 40m !!!

So it should be possible to beam a narrow radar detection beam onto a target up to 50m away.

Great results, indeed!

<joke mode on> I suggest you to stop with experiments at 40m if you don't want to have a midnight MIB visit. </joke>
