Adjustable low voltage occupancy sensor
First Claim
1. An occupancy sensor comprising:
- a front cover having an opening;
a lens assembly coupled to and located in the opening of the front cover, wherein the lens assembly comprises;
a ring shaped member;
a fresnel lens coupled to a side of the ring shaped member,wherein the ring shaped member and the fresnel lens are non-removably coupled to the front cover;
a back cover; and
a base assembly, having a radiation detector, the base assembly is coupled to the front cover and is rotatably coupled to the back cover to provide greater than 90 degree angular orientation to the lens assembly by manually rotating the front cover.

Abstract
An occupancy sensor having a replaceable cover with a convenient adjustment and installation scheme is disclosed herein. More particularly, a single or multi-technology occupancy sensor, assembled inside a semi-spherical shaped enclosure includes a replaceable cover with a convenient adjustment and installation scheme. This sensor design enables the sensor to be rotated after installation to obtain a desired coverage patterns. Specifically, the housing for the occupancy sensor includes a front cover having a lens assembly, a base assembly, a harmonic wheel, and a back cover. The front cover couples to the base assembly such that tool-less, manual access is available through the manually removable cover assembly to adjust several features of the sensor. The harmonic wheel enables the front cover, which includes the lens to swivel from zero to 359 degrees relative to the back cover anytime after installation.
