Controlling a low voltage lighting system with an occupancy sensor is an extravagant and energy efficient addition to a variety of low voltage lighting applications around your home.  Low voltage lighting is becoming increasingly popular in DIY home projects and renovations because it is inexpensive, low maintenance, and easy to install.  While it can be used in practical applications such as security lighting, under cabinet lighting or to illuminate trip hazards in a dark backyard patio, it is also used as accent lighting in bookshelves, cabinets, and gallery spaces.  

In most cases, an occupancy sensor can be added to your low voltage lighting kit to supplement and further enhance the practical and aesthetic features in many ways.  Often these lighting kits are installed and then frequently ignored because they are not essential lights for everyday activity.  But if they are controlled by an occupancy sensor switch they will automatically turn on when the space is occupied and turn off when the area is vacant for a designated amount of time.

Occupancy sensors are so easy to install that there is no reason not to add one when installing your low voltage lights.  Low voltage lighting kits tie into standard voltage electricity in one of two ways: 

a) a transformer that plugs into a standard outlet receptacle, or
b) the transformer gets hardwired into the residential conduit.  In each circumstance there is an opportunity to introduce an occupancy sensor switch into the circuit. 

In circumstance 'a' plug the low voltage lighting transformer into a wall outlet that is controlled by an existing light switch.  Replace the existing light switch with an occupancy sensor switch.

In circumstance 'b' find nearby conduit and splice an occupancy sensor into the conduit and wire the transformer to the
switch.  In this configuration you can choose to install a ceiling mounted or wall switch mounted occupancy sensor; whichever best suits the layout of the space or application of the lighting.
