Effective Ways To Detect People With Common Sensors

why are you gay

Was not aware of the mm wave sensor. I have been trying to get other sensors mentioned here to work but there was always some kind of an issue or other. This mm wave sensor may be just what I want. Thank you! Off to order one.

great video. thanks!

If I recall correctly, you can change the sensitivity and duration of the pulse on the RCWL-0516 radar sensor by changing the values of the resistors on it. My only complaint about that sensor is it has a wide detection bubble around it, and since they can "see" through walls, you can't confine their detection area to a single room.

A clever dog uses a a PIR sensor to trigger an active detector. This reduces power requirements and reduces false positives

Great comparison :-) Though i think the Radar sensor can be changed by altering the resistor or capacitor on the board.

What a great channel! It would be cool to see an outdoor version with rain and sunlight as factors.

bro out of this which sensor can i use to gather enough data for the object future path prediction?

The problem I found with PIR sensors is that the standard ones are too cheap and unreliable, especially when range of over five metres is required. I upgraded to a Panasonic EKMC1603111 and despite having no adjustability it reliably detects movement up to 12 metres or more. Including vehicles, which is something the standard sensors couldn't do even on maximum sensitivity.

Thank you, most informative.

Need some weight/touch sensors in there..

I did a project with the first green microwave sensor shown. Worked amazing for sensing people coming into a room or for what I needed it for... to sense people walking down a forest path.... one problem...as soon as the environment around was wet or damp (like rain or morning dew) it was completely blind. I assume what is happening is the microwave signal is being absorbed by the human or wet surface so both send back a shadow....so no movement detected when everything was a shadow. Worked fine in the garden when dry. One to watch out for. Otherwise awesome!

I am aware of the sensors but i didn't knew about the drawbacks of the sensors that you have mentioned. it was informative and expecting more such videos...

I'd love to see these sensors applied to detecting when some crook tries to jump under your car to steal the catalytic converter. Hint, hint... video idea....

Awesome !!, Thank you so much, that was really informative 🌹

Very helpful. I see all these components for sale but it's hard to tell from the datasheets how they perform in actual use.
