Post project 35: Capacitive Proximity Detector
With this circuit you can
detect the presence of an
object from some distance away, depending on the sensitivity and the size
of the object. Very handy for detecting whether someone is on the other side
of a door without first having to open the door!

You can, for example, use this circuit to detect people, but you can also use it to detect the presence or absence of the car in the garage. It doesn’t matter whether the detected objects moves or not, it only matters whether an object is within a certain distance of the sensor.
