Abstract
A programmable controller for controlling an ultraviolet (UV) sensor may adjust an excitation voltage provided to the UV sensor based at least in part on a programmable sensitivity offset in order to produce an excitation voltage that results in a desired UV sensitivity for the UV sensor. The programmable sensitivity offset may be set for the UV sensor at the factory, set during commissioning of the UV sensor in the field, and/or automatically altered over time to help compensate for a degradation in sensitivity of the UV sensor.
