Occupancy sensors employ the use of technologies like infrared (which detects heat emitted by human bodies), ultrasonic (which uses sound to detect movement), microwave (measures reflections to gauge movement), and more to detect the presence of individuals within a space and trigger automatic responses as a result. This will send signals to other systems in the building such as lighting, HVAC, and security to act accordingly. Technology like this goes a long way towards cultivating a smart building and saving energy and money.
The Benefits of Occupancy Sensors
Energy efficiency is a big plus to investing in occupancy sensors; these can send signals to automatically turn off lights and adjust HVAC systems in unoccupied spaces. Security can be enhanced by detecting unauthorized access and trigger alarms, and for heightened safety, falls and other emergencies can be monitored through movements and (in advanced sensors) vital signs.
Optical sensors generate low-resolution images of a space and convert them into binary data through the use of AI technology. To ensure privacy, these images are deleted immediately and only the binary ones and zeros are sent to the company’s system so the data can be put to use in making decisions to optimise the building and make any necessary changes.
A study by the Environmental Protection Agency in 2001 found that occupancy motion sensors can reduce energy waste by up to 68% and increase energy savings by up to 60%. The Carbon Trust recommends occupancy sensors, stating they can help reduce electricity use by 30%.
Sensors like theMilesight VS341 desk and seat occupancy sensor is a discreet device that works wirelessly for quick and accurate occupancy status updates. This device works for anonymous detection and is made to be tiny and non-invasive whilst delivering great results. PIR and thermopile sensors fully capture the motions and temperature variations within its target area, freeing up human resources and contributing to trustworthy results.
If you’re aiming to save energy and optimise your building with smart sensors, occupancy sensors are a reliable solution. They improve overall efficiency, mitigate misunderstandings about space occupancy, and enable more effective energy consumption monitoring. Additionally, they enhance space management and foster a more comfortable and productive environment for everyone in the building.
On the side of maximising safety, they can also help in case of a fire; tracking the occupancy of a space will ensure you get everyone out in a timely manner. By doing this, you can also avoid any legal disputes that may arise if human error plays a part in missing occupants during an evacuation.
Occupancy sensors contribute to more accurate data collection, facilitating better decision-making regarding space utilisation and energy management. Overall, integrating a people counter sensor into your building management system not only conserves energy and reduces costs but also enhances safety and operational efficiency.
