Ceiling Mount Occupancy Sensor Switch
29th May 2021


Occupancy sensors are the sensors that switch on/off the lights by detecting people around them. It switches on the lights when it identifies the people around it and automatically switches off the light when no person is there. It helps in saving electricity and provides better facilities for the modern world. Nowadays, they are installed at various places like offices, classrooms, toilets, dressing rooms, etc. According to the needs of the modern world, we also have to update faster.

An occupancy sensor is a device that detects that whether a person's presence so that lights, temperature, and ventilation systems can be controlled automatically, or so they thought. Ultrasonic, fairly infrared technology kind of is used in the sensor, which is quite significant. These sensors are usually used to save energy, which is quite significant automatically literally. Lights are turned off automatically when the place is vacant, and they are turned on when someone mostly is present in a big way. For the most part, these sensors have a manual option also where the person can work manually on or off the device, which generally is fairly significant. There are two types of sensors, which is fairly significant.

 

More about occupancy sensors

· It helps in reducing the wastage of energy and cost.

· It is most effective in the modern era as a human being is living a busy life, and many times, he skips the switching off the lights.

· It covers a larger area, and its installation system is so easy.

· Investment in these Sensors is very good because the return on this investment is high, and these sensors can quickly pay for themselves.

· Sensor switch offers a wide range of a sensor for the high bay application.

 

Types Of Sensors

      · Microwave Motion Sensor: these sensors detect motion through the principle of Doppler radar, and are similar to a radar speed gun. A continuous wave of microwave radiation is emitted, and phase shifts             in the reflected microwaves due to motion of an object toward (or away from) the receiver result in a heterodyne signal at a low audio frequency.

· Passive infrared (PIR)When a person enters the room where this PIR sensor is installed, it detects the temperature change and turns on the lights. It is easy for this type of sensor to detect the movement of a person. It also works smoothly in small and covered places. They are best in detecting major movement.

· Ultrasonic TechnologyWhen a person enters the room where this ultrasonic technology in sensors is used, it detects the change in a frequency shift in the sound waves and hence turning on the lights. They are best in detecting minor motion.

· Dual TechnologyThis type of technology used both PIR and Ultrasonic technology. These sensors are more updated than the above two sensors discussed above.

· Stairwell or elevator are the devices that require this type of energy whereby the presence of person device get started and get off when there is no one present.

· Microwave sensors find changes in occupancy by emitting low-power microwaves.

· The camera sensor is designed so that it takes multiple images of the coverage area per second.

· PIR sensors that work on the heat emission find motion within the coverage area only.

· US sensor works by producing an ultrasonic high-frequency signal in the area and finding the changes in the frequency emitted. These types of sensors are highly detective.

 

 

Usage of Occupancy Sensors

· It helps in cutting down the energy consumption level by which we can save overall electricity bills.

· They are also used in four-wheelers. When we open the door of these vehicles, then the lights are automatically switched on.

· Usage of these sensors is also in refrigerators.

· These sensors are also used in warehousing centres, big industries, and distribution centres.

· Small areas cannot adjust to such a high mode of occupancy and hence result in the wastage of our cost and money.

· We can invest as return on these Sensors are very high as it saves so much energy and our electricity bills.

· These sensors can quickly pay for themselves.

· The need of the modern age to use these sensors as the resources are scarce, and it isn't easy to generate electricity due to its high use. So we can cope up with this challenge by using these modern world sensors.

 

Working of the sensor switch

 One is a passive infrared sensor that works on heat. When they detect heat, they turn on the device by sending an electrical signal. Another one is the Passive infrared sensor which works on the Doppler effect, which is also used in the car. A combination of two sensors can also work, which is called dual technology sensor. It comes with both the feature of manual, partial, or full-on devices. Manual On sensors are also called vacancy sensors, requires the consumer to turn on the light manually. The partial sensor then activates 50% of the light, and the usage of the switch brings it to full output.

 

 Winding Up

The very much the best sensors are the occupancy sensors, which help keep the vehicles' continuous track. Occupancy sensors particularly are placed in buses, trucks, and cars in a big way. The cost of the application of these sensors is very kind of cheap in a major way. There are various sensors with different styles and different coverage areas of pattern, which is particularly significant. But among all of the occupancy sensors, particularly, are best in a really major way. Voltages of sensors particularly vary as all sensors have different voltage power, which is quite significant. For the most part, some sensors have a 360° coverage area of a pattern, whereas some have a very low coverage pattern in a fairly major way. For the most part, we have hundreds of designs, and you get options to choose which design suits kind of your device. 

With the help of these sensors, energy wastage mostly is pretty much less, and one must use it to save energy, and even for all intents and purposes helps to save money, which is fairly significant. For the most part, it leads to energy saving up to 24%, definitely contrary to popular belief. Manual and partial sensors save more energy than any generally other sensor in a major way. Researchers mostly find new technology such as light kind of differential sense, contrary to popular belief.
