All that You Need to Know About Ceiling Occupancy Sensors

Ceiling occupancy sensors are high-tech devices designed and developed to detect whether a designated space or room is occupied or unoccupied. Accordingly, it will turn off and on the lights, fans, and other electrical appliances, thereby saving substantial energy. 


The price of occupancy sensors is pretty reasonable. They are easy to install and use, and due to their high energy-saving properties, they are extremely popular. The fact that they have several energy code mandates has made these sensors a staple for modern buildings – both domestic and commercial. 


What inputs do they need? 

These occupancy sensors can be categorized into three types - manual, partial, and full ON devices. In most commercial buildings, the energy codes need a manual or partial-ON operation. The Manual-ON sensors, also termed vacancy sensors, need the occupant of the space or room manually switch off the appliances. It will activate the sensor if the switch is integrated with the sensor circuit. 


The Partial-ON sensors activate the appliances to a particular predetermined designated level (like 25 or 50%) and then the occupant has to use a switch to get the full output of the appliances. FULL-ON sensors, on the other hand, will instantly activate the appliances to their full output. 


The Manual-ON and Partial-ON sensors save more energy than the FULL-ON sensors, with the latter providing more convenience, and it is often regarded as an added amenity. 


What are their outputs? 


A ceiling occupancy sensor (or a vacancy sensor) may turn off the lights and fans or can reduce their output with the help of dimming or stepped switching. While the ON/ OFF mode is pretty common, the light or appliance output reduction is applicable in cases where the light and the fan must remain functional even if the room or the space remains unoccupied frequently – for instance, the stairways. 



The Coverage pattern and Area 

The sensitivity of the modern sensors defines the distance from which the sensor can detect the entry and exit of the occupant and the area circumference it covers. This resulting coverage range is termed as coverage pattern and area. In other words, the coverage area expresses the boundary within which the sensor will work and detect the motions. Now the shape of this area may differ and can be circular, elliptical, rectangular, teardrop, and so on.

How to Plan Occupancy Sensor Layout?

Image
Covid safe protocols and social distancing in the workplace may be the first thing that comes to your mind when thinking of re-opening the office after Covid-19. While you may control the number of people in the office using badge swipes, how the employees use the space needs better monitoring. Here is where the occupancy sensors come to work. These devices can detect the presence of people within a given space. These smart devices can monitor occupied areas like conference rooms, work floors, and workstations. However, the placement of the occupancy sensor needs to be strategically planned to ensure that it gives you the desired results. Let us check a few factors that you should consider when installing occupancy sensors . Use Real-Time Data If possible, use real-time data on how the office space is being used currently. It will give you an insight into how to place the sensor. Usually, one occupancy sensor can cover up to 1100 square feet. Hence you might divide large spaces into z

3 Ideal ways to use occupancy sensor data for ROI reporting

Image
  Every organization requires accurate data in order to make appropriate management decisions. And while occupancy sensors can provide real-time data, the essence lies in effectively using the findings to ensure a better ROI. Here are the three key occupancy sensor metrics that you should focus on to ensure proper office space planning for better ROI. Density The fastest way to ascertain whether your space requires consolidation or expansion is to analyse the density data. Information from such data can help determine the demand by specific groups or departments for a specific space, such as office floors or particular departments. The density of a space is determined by dividing the total square foot by the total number of users. This value will help to determine the appropriate room occupancy sensor needed for your office space. Its people counter feature collects real-time data relating to the density of people in your premises at different hours of the day. This will help you cre

Merits Of Using An Occupancy Sensor

A considerable percentage of corporate assets are in real estate. In most cases, the total cost of occupancy of corporate real property is approximately half of its net income. So, when an organisation is spending huge amounts of money on office space, they would want to ensure that the spaces are right for their needs and that they are getting their money’s worth. One way to ensure the space is optimally utilised is by using occupancy sensors. Through monitoring office space usage, informed decisions can be made on using the space in the best manner possible. Although smaller organisations may be hesitant to use sensors due to occupancy sensor prices , the benefits of using them make the investment worth it over time.   What exactly is an Occupancy Sensor? A device that detects motion and recognises when people have entered or exited an area or room is called the occupancy sensor. Although an occupancy sensor detects motion, it is different from a motion sensor as it has far greater
