Abstract
A sensor system useable in conjunction with one or more environmental fixtures is disclosed. Each of the fixtures preferably includes illumination functionality as well as UV sterilization functionality provided by a fan and UV LED chips in the fixture. One of the fixtures is preferably programmed as a master which executes a control algorithm to control and/or monitor the system. The sensor module includes a plurality of sensors for sensing different environmental conditions where the system is utilized. These sensed conditions are provided to the master fixture, whose control algorithm can use the sensed conditions to control one or more functions in each of the fixtures, such as illumination, UV sterilization, and/or fan speed. The master fixture can output necessary controls to other secondary fixtures in the environment. The system may further communicate with or include external devices that can wirelessly communicate with the system using an application.
