FAQs
How do occupancy sensors detect movement?
Occupancy sensors detect movement in various ways, including passive infrared (PIR), ultrasonic, microwave sensors, or a combination of these. For instance, PIR sensors operate by sensing changes in infrared radiation emitted by humans or warm objects, while microwave sensors emit low-power microwaves and measure the changes in the reflected signal caused by movement. Ultrasonic sensors emit high-frequency sound waves and measure the reflections to detect movement. This sensing technology is used to detect occupancy and trigger an action, such as turning on lights or activating security systems.
What are the benefits of using occupancy sensors in a building?
Energy savings
As occupancy sensors are designed to automatically turn lights and other electrical devices off when a space is unoccupied, they help to conserve energy by eliminating the need for constant use. By reducing energy use, businesses can also reduce their energy bills in the long-term.
Convenience and comfort
Occupancy sensors eliminate the need for manual switches and create a comfortable environment by automatically turning on lights when someone enters a room or controlling heating and ventilation.
Safety and security
An occupancy sensor is an effective tool for improving safety and security. For example, in public spaces they ensure that areas are adequately lit when occupied, reducing the risk of accidents and providing a sense of security for people in areas with limited or no natural light. Automatic lighting can also deter potential intruders by signalling the presence of others nearby.
How can occupancy sensors improve building security?
Advanced occupancy sensors can be integrated into existing security systems to detect motion in private or restricted areas. This motion can trigger alarms, activate surveillance cameras or send an immediate notification to a nearby security team to quickly prevent any potential security threats.
How do I choose the right kind of occupancy sensor for my needs?
From flush mounted to surface mounted, wattage and size, there are lots of factors to consider based on the requirements of your space. We recommend evaluating the range and coverage area of the sensor to ensure it covers and monitors the desired space, and considering useful features such as adjustable sensitivity, time delay settings and compatibility with other systems you have in place.
