Sensing Opportunities: Pros and Cons of PIR and Microwave Approaches
Lighting the great outdoors requires a bit more thought now than it did a
couple decades ago. The goal used to be simply packing as many lumens
as possible into a landscape fixture. That was the entire point.
Photocell sensors might have been used to ensure lights didn’t stay on
during daylight hours, but keeping outdoor space fully illuminated –
even when no humans were around – was seen as a key safety measure.

Less Work to Meet Safety Requirements
Some facilities are changing their requirements for motor and appliance
installations. This could be due to OSHA Lock-out and Tag-out
requirements or NFPA 70E. The change is toward using pin and sleeve
devices instead of having a hard-wired installation.
Safety requirements often have the maintenance person checking for the
absence of voltage before touching. The rules are quite specific and are
enforced by OSHA.
