Motion Detectors

An Overview for the Motion Detectors

What is it?

Motion detectors are devices used to detect the movement of people or objects in heating, ventilation, and air conditioning (HVAC) systems. They can be used to trigger alarms, activate lighting or HVAC equipment, and enhance occupant comfort.

Why we use it?

We use motion detectors to improve energy efficiency, increase security, and enhance occupant comfort by regulating the use of HVAC equipment and lighting in buildings.

How it works?

A motion detector typically contains sensors that detect changes in motion within a specific area. When activated, the detector sends a signal to a building automation system or controller, which can then adjust HVAC equipment, lighting, or other systems accordingly.

Major brands that manufacture it

Some of the major brands that manufacture motion detectors include Bosch, Honeywell, Leviton, and Lutron.


There are different types of motion detectors, including passive infrared (PIR), ultrasonic, and microwave models, with various sensing ranges and control options to fit different applications.

How do we select it?

When selecting a motion detector, consider factors such as sensing range, sensitivity level, environmental conditions, and communication protocols. Also, make sure the detector is compatible with your existing control and automation systems.

How to install it?

Motion detectors should be installed according to the manufacturer's recommendations. Sensors should be mounted in locations where they can effectively detect motion, while any necessary wiring connections should be made to the building automation system or controller.

Wire connections required to receive the signals

The wire connections required to receive signals from a motion detector may vary depending on the specific device and building automation system. Typically, they will require electrical wires that connect to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
