- The invention of radar influenced the way World War two went because it was possible to detect planes of the enemy and shoot them down. And since then, this technology made civil aviation as we know it possible because it can detect the movement of metallic surfaces over distance. Of course, technology can also be used against us, for example, if we are trapped while speeding…

As many commenters rightly found out, these devices are regenerative receivers. If you are interested in "real" radar sensors, I propose watching video
Here is a whole new exciting frontier for conspiracy theorists!!!
Hi. I've recently discovered the RCWL-0516 and in search of more specifics I've then found your video.Your extensive tests are very helpful. Especially the needed voltage to run it, the diagnosis if the devices interfere with each other, the directionality and what they penetrate.
Today my RCWL-0516 's arrived from ali-express, could'nt wait to do some experiments .. (did'nt add any additional components)
Andreas , Thank you for your articulate understanding of this technology.
I just come across one of those sensors and landed here after googling. Geat info!
Sir your videos are gold, it reflects how much work you put into these masterpiece review videos.
Mystery gadgets! Nice writeup. You have a very comfortable voice and clear, easy to understand diction. Good job!
Thorough review that answered all my questions.
Nice introduction in Mircorwaves. I like your channel very much.Also becaues you are a swiss guy too :) It's very nice to see, that we have such brillant heads in our small country ;) Since 3 days I played around with the RCWL-0516 and I'm very happy with it. Stay healthy and I hope a lot more videos are coming up :) Next I want to build a LoRa Gateway because in my region no one have it. A liebe Gruess und sunnigs Wätter :)
excellent comparison video, I can see allot of work went into making this.
Perfect timing! I just received four RCWL-0516 units. I could not decide which variety to get and it appears randomness intervened to select a good choice for me.
thank you so much for doing this test its very important for many useful applications !
The long awaited radar sensor comparision you promised to do! You have not forgotten it! Now I know these devices work and which one to buy. Thank you so much!
"of course the technology can also be used against us" LOL
I keep repeating myself... great video !
Good to follow the thought process.
I discovered those modules recently, and still waiting for them to arrive. You saved me a lot of time, i don't have to make a comparative test. Thank you
I have been using RCWL-0516 Microwave Radar Sensors in a smart lighting application (integrated with ESP32 developer boards) for several months now. To this video I would add a couple notes. The first is that though the sensors do not interfere with each other, they can get false triggered from the ESP32. This effect falls off after a centimeter or two. Lesson learned, be careful mounting the sensors to the same circuit board as your controller. The lack of directionality and ability to penetrate wood is amazing and perfect for my application. The sensors often detect me just before I enter the rooms with my lights.
I don't usually like videos on request, but I had to make an exception.
