Occupancy Sensor Working and Its Applications

An occupancy sensor is an electronic sensor, used for different purposes like to improve the security of the office as well as home, reduces the energy utilization for lights in empty spaces. Generally, this sensor unites a motion detector using a timer as well as a light switch to activate and deactivate the lights as they are not required. These sensors can be connected to an alarm for the purpose of security. By using these sensors, one can conserve the energy without needing main changes. This sensor can be used to detect the vacant to deactivate the lights after a specific time period based on the used sensor. There are different kinds of motion-detecting sensors available in the market, but these sensors fall under one of these categories like active & passive.

What is a Occupancy Sensor?

An occupancy sensor can be defined as it is a motion-detecting sensor used in indoor used to sense the incidence of a person for controlling lights automatically. These sensors use IR, microwave, ultrasonic, otherwise another technology.

The name includes the devices like keycard locks in a hotel room, PIR sensors, as well as smart meters. These sensors are normally used for conserving energy, and provide automatic control, and follow with codes of building.

Types of Occupancy Sensors

There are different kinds of occupancy sensors which can be combined by using various motion detectors and devices like PIR, microwave emitters, ultrasonic emitters, etc

  • PIR (Passive Infrared) Detector
  • Ultrasonic Detector & Combined PIR
  • Active Ultrasonic Detector
  • Passive Ultrasonic Detector
  • Environmental sensors
  • keycard light slots
  • Smart meters
  • Occupancy Sensor and Microwave Detector

Working

Occupancy sensors are one kind of devices used for detecting whenever space is empty then it is automatically deactivated the light so that the energy can be conserved. This sensor may also activate the lights.

This device can also activate the lights routinely by detecting the occurrence of people and provides security and convenience help. Based on the laboratory like Lawrence Berkeley National, the strategies based on occupancy can generate 24% of normal savings of lighting energy.

Because of their energy conservation and relative simplicity, these are united with energy code permissions. These sensors are used in the latest construction and also it has a general control feature used in retrofit projects.

Application of Occupancy Sensor

These sensors are frequently used within indoor places for activating or deactivating electric lighting. When space is empty then it can be assumed that there is not moving can be detected. So doesn’t need to turn ON the light. The energy can be conserved by deactivating the lights. In some cases, these sensors called vacancy sensors or presence sensors. The best examples of occupancy sensors mainly include Ecoamicatechs Sirius, Philips Lumimotion, and LSG’s Pixelview. By using image processing, these sensors classify the no. of residents, and their motion direction, etc. The camera-based occupancy sensor is a pixel view which uses a camera that can be built into every light fixture.

Thus, this is all about Occupancy Sensor and its working with an example. Here is a question for you, what are the advantages of an occupancy sensor?
