Occupancy sensor and motion sensors are also known as detectors. The purpose of occupancy sensors is to detect when someone is in a room. When someone is detected in a room the lights will turn on. When the person leaves the room the lights will turn off. In some circumstances it does not require the person to do anything but enter the space and leave the space. Some wall sensors require the person to manually push the sensor switch to activate the sensor then when sensed the lights will turn on. When leaving the room the person has a choice to manually turn the lights off or the timer built into the sensor will automatically turn the lights off after a pre-determined set time once no detection is noticed.
There are three general types of technologies an occupancy sensor utilizes for detection. (PIR) Passive infrared, ultrasonic and dual technologies.
PIR distinguishes between body heat and background heat. Ultrasonic sensors sound out ultrasonic sound waves and look for frequency changes by a moving person. Dual-technology sensors use both PIR and ultrasonic technologies, activating the lights only when both technologies detect the presence of occupants. PIR requires a line of sight where an ultrasonic does not. Ultrasonic are more sensitive than PIR occupancy sensors.
Manual-On occupancy sensor:
The unit will not turn lights ON automatically when motion is detected. Lights can only be turned ON by manually pressing the push-button. The lights will remain ON as long as the unit detects activity in the sensor zones. California occupancy sensors are required in what locations and under what Title 24 energy conservation laws set rules as to what type of circumstances.
