PNP Proximity Sensor vibration sensor arduino meet your needsA PNP proximity sensor is a type of sensor used to detect the presence or absence of an object without making physical contact. PNP refers to the transistor type used in its output stage, where the current flows from the sensor's output (positive voltage) to the load. When the sensor detects an object, it switches on the output and allows current to flow to the load. Operating Principle: The sensor uses electromagnetic fields, capacitive fields, or
