Occupancy & vacancy sensors are small devices designed to
detect the presence of a person in a room and accordingly adjust the physical
space to the optimal state. These sensors control light, shade and temperature depending on the presence of people, time of
day and general weather conditions. Not only is this unique technological
invention trendy and appealing due to the lack of effort required to operate
the various installments in a room but it is also an ecologically friendly and
cost efficient investment.
Now let's see how these sensors have a positive impact of
your finances and the environment. From a young age we are told to turn off
lights and fans when we leave the room, but how many of us actually remember to
do this? Now, it might seems like this is not a large enough concern for many
but when we think about centrally air-conditioned spaces where we spend most of
our time such as offices, malls, restaurants do you really think about asking
someone to turn the temperature of the AC down or turn of the lights when you
leave the bathroom? These costs that where always considered fixed are what
occupancy and vacancy sensors attempt to reduce, not to mention the positive
environmental impact! The occupancy and vacancy sensor can even play a impactful
role in residential situations. The light sensors can prove to be crucial in
housed with small children to ensure safety, during the evenings and at night,
as well as responsible use of electricity. Let's admit it. Children never turn
off the light!
While Occupancy sensors have been around for some time, what
has changed is the way they operate and the technology they adopt. For e.g the
earlier motion sensors worked on passive
IR Technology where in a major motion was required between the various IR rays
emitted by the sensor- for the sensor to detect presence. While these worked
fine with places such as hallways and pantry areas, they failed where the
motion was very small- such as when a person occupies the office or uses the
bathroom. The latest technology sensors are able to detect even minor motion
and hence will generally not turn the lights off when you are sitting still and
working on your lap top (say). In fact this ability to detect even minor motion
could be the main reason for pricing differences, in addition to the sensor
coverage areas and the technology they use to function.
Anusha Technovision offers the Radio Power occupancy
Wireless sensor through its partnership with Lutron which is equipped with the
best technology within the occupancy and vacancy sensor market at the moment
complete with daylight sensing ability – for homes as well as for commercial
office spaces. These sensors can be stand alone or part of a larger Lighting control system. When they are part of the lighting control system they can be
made intelligent for e.g a home owner
could decide that his bathroom lights should turn on every time he walks into
the bath room but it should happen only at night time , and in day time he has
to manually turn lights on. The sensor of course turns lights off when the
bathroom is unoccupied. “Occupancy
sensors can be called the foot soldiers in the fight to conserve energy.” As
per Alok Hada Director ATPL.
