Multi-Pixel Technology detects up to a certain distance but not beyond that, and can also define sensing windows within which objects are sensed. MPT sensors are flexible enough that multiple distances can correspond to multiple outputs of the same sensor. Pulse Ranging Technology can measure distance along a line of sight and calculate the dimensions of an object, or detect objects within a certain distance or range. simple presence detection, a conventional presence sensor is ideal. But when some objects must be seen and others ignored, or an object must be seen only at certain locations, or when the object's presence and its position must both be known, SPT, MPT, or PRT distance-based sensors are the best options.
