Occupancy Sensors

Wasting energy on lighting common areas that are unoccupied can result in exorbitant energy bills. Occupancy sensors detect when people are present in a room and turn the lights off after a certain length of time has passed since the occupants left. Installing and using occupancy sensors in shared areas such as restrooms, gyms and conference rooms can result in up to 50% energy savings | Learn More > 

Passive Infrared (PIR) sensors implement heat difference detection by measuring infrared radiation. These sensors detect the presence of objects (such as people) that radiate a temperature that is different from the temperature of the background. 

Environmental sensors detect the change in environment due to the presence of humans. Such changes include temperature, humidity and carbon dioxide (CO2) levels.

Ultrasonic sensors utilize technology that is similar to radar; they work on the Doppler shift principle. An ultrasonic sensor sends high frequency sound waves in an area and checks for trajectory changes and reflected patterns. If the reflected pattern changes, it assumes that there is occupancy.

Microwave sensors works similarly to ultrasonic sensors. These sensors usually have high sensitivity and detection range compared to other types of sensors.

Keycard Light Slots detect when a hotel room is occupied by having the guest place their keycard in a slot to activate lights and thermostats. This is a great method to implement in guest rooms for reducing energy consumption.

Smart Meters detect the change in power consumption patterns that are associated with distinct characteristics for occupied and vacant states.
