We are trying to build a circuit that can sense if a human is wearing the helmet(for motorbike) or not.....we are placing it inside the helmet so it needs to be really small. Which sensor should we use?

What will the sensor do with the information? Is it wireless?
I would have thought a parallel array of tactile switches inside the top would work.

You have to think about the sweat, heat and air circulation as well.
Some form of 'break beam' LED sensor placed either side may work.

It is wireless....will think more if we can implement a break beam kind.....but due to vibrations that needs to placed accordingly.... thanks for your reply....is there any other way of doing it?

Hello,

What should the sensor do with this helmet?

You will likely need a camera with a lot of calculation power for "seeing" the helmet.

Have you considered using a temperature sensor (or 2)? The temperature within the helmet should be much warmer than outside when worn by a human. If not worn, inside and outside temperatures should be close to each other.
Temperature sensors are small, inexpensive and can be bought in quite robust versions.

Any add on like this tends to be forgotten as one dismounts and tears the power supply cable out or.......
creates a short and makes for an interesting if not dangerous sudden stop by the rider.....seen lipo blowouts on youtube...???

Apart from that, the inside of the helmet is designed to protect ones brain, not to house odd bits of add-on electronic devices that would punch holes in ones noggin.
