Abstract
A detection sensor with a single switch for multi-function programming of the sensor is disclosed. The sensor has a processor operatively connected to the switch, an emitter, and a detector for controlling one or more operational parameters of the sensor in response to a program signal from the switch. In the preferred embodiment the processor compares a signal detected by the sensor in a first state and a second state and automatically establishes the sensor amplifier gain and switching thresholds based on the signal difference in the two states.
