An inductive proximity/distance sensor that can detect metallic objects at close range. As soon as a metal object is detected, the signal wire and ground are connected with a transistor. If no object is detected, the signal wire takes the voltage of the power supply through the built-in pull-up resistor. For example, the sensor can be used in 3D printers.
