Abstract

In an example embodiment, an improved lighting controller designed to reduce the effects of electromagnetic interference is introduced. The improved lighting controller contains software that acts to filter input lines so that noise is ignored while legitimate pulses coming from sensors are handled. The software filter works by comparing pulse widths of pulses on input lines to an expected pulse width.
