Hey all,

I am developing a system, that part of it is to detect car presence, I want to install a device that sensing if there is or not a car above it' and to send it wirelessly.

what can you suggest for me for detecting the car presence? I know in general that we can use magnetometer in a tricky way to detect, what I need is to have a device powered by battery to last for about 5 years, and that presence of subjects above the sensor would not make fake measurments so I think I have to detect a big mass of metal which is equal to car presence.


which devices can you suggest for me to use for this?
