There are, however, specialty models with dimmer capability. Dimming: Most motion sensor lights do not function as dimmers.Daylight sensors have dials that let the user customize the sensitivity. If the sensor detects that the room is already bright enough, it will not turn on the lights. Daylight sensing: Sensors assess the level of ambient lighting in the room and turn the lights on or off based on that level.Motion sensor light switches include extra functions that allow the user to customize how they work. To avoid accidental triggers from sunlight, the sensor’s sensitivity allows it to ignore gradual changes in heat. If the sensor detects no body heat after a certain amount of time, it triggers the switch to turn off. If the sensor detects heat, it triggers the switch to turn on. A passive sensor detects heat given off by people and animals.If the sensor doesn’t recognize any changes over a certain length of time, it turns off the light. If the returning waves identify a change in the pattern of the objects in the room-because someone has entered or is moving in the room-the sensor triggers the switch that turns on the light. An active sensor sends out sound waves that bounce off people and objects in the room and then returns them to the switch.Motion sensor light switches use one of two sensors to detect occupancy in a room: passive and active. Occupancy light switches, in comparison, will turn on the light regardless of the brightness level in the room, unless they have a light sensor. However, vacancy light switches automatically turn off the light after the room has been unoccupied for a certain period of time.Īlthough vacancy light switches may not be quite as convenient, they are more energy efficient as the user may often not need artificial light in a room when there is enough natural light from windows. Vacancy light switches do not turn the light on when a person enters, requiring them to turn it on manually.Occupancy light switches turn on the light when a person enters the room and then turn it off a set amount of time after they leave.Motion sensor light switches are available in occupancy and vacancy types, with many functioning as both types. Ahead, learn about the two distinct types, the difference between active and passive sensors, and other critical characteristics of these convenient electrical devices. Though a motion sensor light switch performs the simple task of turning on or off the lights in a room, there are a surprising number of factors to consider when shopping for one.
