Sensor requirement

[AK05]

Which is the best sensor to detect static human presence. It needs to sense if a rider is wearing a helmet or not(for motorbike).

I would guess a camera with (very good) object recognition software.

Sir...Can you suggest a sensor?

 

[Pommie]

I did, a camera.

Sir...The sensor has to be placed up close to the subject...almost touching the subject.

So thought that we can't place the camera is that position.

When you say "detect a person", what else may be present that you don't want to detect (a small dog, a large dog, an ape, shadows of people, a humanoid robot...)?

Or are you only checking if a person is present or not present with no interfering objects possible?

What kind of area do you want to sense (Entry door to a room, a computer chair, an entire room, a park or forest)?

If that is your requirement, then have a look at a capacitive proximity sensor.
