“Quick! How can we use this to gather data for ad targeting?”
I’ve played around with this (the KIT-CSK-BGT60TR13C). It is a very interesting gadget and the kit doesn’t need much configuration. In an afternoon I made a car detector for my bike that detects the presence of an approaching car from behind. I thought I had a winning startup idea then found out this idea has existed for years. :(
Pleasantly surprised to see electronics parts manufacturers on front page HN. The advancement of sensors nowadays is staggering - I'm reminded of the recent airborne dust sensor that's literally orders of magnitude smaller because it uses a new backscatter detection mechanism. All this technology available at very reasonable prices too.
It is nice to see more technically oriented things on the main page. It is frustrating to see very high level more businessy topics.
Also, 15usd is not cheap for this kind of chip. You can buy a full wifi 7 rf/modem or a 4 core arm64 soc with this kind of money.

I'd like to know about this product, got more info? Not a bot, just a cyclist who's fed up of drivers who don't care about my safety.

This is a phased array device. Angular resolution 20 degrees, range resolution 1 meter. It's not a Doppler radar, so it can detect fixed objects. So if you're using it for people detection, you have to tell it where the fixed objects are. A ceiling mounted unit will see the floor. OK for people counting and such. Range is only 10 meters.
If you just want a motion detector to turn on a light, and IR isn't working for you, there are cheaper microwave detectors.

Amazon with all its power and incentive still can’t figure out there’s a limited number of toilet seats I might need. Linkedin is still offering me (50ish male, 30+ years in it, 15+ years of teaching in universities, board member etc) jobs as a kindergarten teacher. If anything, I’m amazed they are still so bad at this.
