09/02/2015· Not all PIR sensors have the same output or even output type. A pull-up resistor is needed when the output type is what's known as a "open collector" (or open drain). These type outputs use a transistor (or a FET) to produce a short circuit to ground, generally when the PIR detects something. When there's no detection, then the transistor is an open circuit and that leaves the Arduino input pin …
