Motion sensor light switches detect motion or body heat, turning on the light when a person enters and turning it off after the person exits. Plus, most DIYers can [trade out an old light switch]() with a motion sensor light switch with just a few simple tools. This guide will examine the essential factors to consider when shopping for the best motion sensor switch and identify some of the top models on the market. 1. **BEST OVERALL:** [Lutron Maestro Motion Sensor Switch]() 2. **BEST BANG FOR THE BUCK:** [ECOELER Motion Sensor Light Switch]() 3. **BEST MOTION SENSOR:** [Leviton IPS02-1LB Decora Motion Sensor In-Wall Switch]() 4. **BEST SMART:** [GE Enbrighten Z-Wave Plus Smart Motion Sensor Switch]() 5. **BEST CUSTOMIZABLE:** [ELEGRP Occupancy Sensor Light Switch]() 6. **BEST WITH DIMMER:** [TOPGREENER PIR Motion Sensor with Dimmer Light Switch]() 7. **BEST THREE-WAY:** [ECOELER 3 Way Motion Sensor Light Switch]() 8. **BEST VERSATILE:** [TOPGREENER TDOS5-W-2PCS Motion Sensor Light Switch]() ![Best Motion Light Switch Options]() *Photo: amazon.com* ## What to Consider When Choosing the Best Motion Sensor Light Switch 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. Ahead, learn about the two distinct types, the difference between active and passive sensors, and other critical characteristics of these convenient electrical devices. ### Occupancy vs. Vacancy Motion sensor light switches are available in occupancy and vacancy types, with many functioning as both types. - **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. - **Vacancy light switches** do not turn the light on when a person enters, requiring them to turn it on manually. However, vacancy light switches automatically turn off the light after the room has been unoccupied for a certain period of time. Although 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. Occupancy light switches, in comparison, will turn on the light regardless of the brightness level in the room, unless they have a light sensor. ### Active vs. Passive Sensor Motion sensor light switches use one of two sensors to detect occupancy in a room: passive and active. - **An active sensor** sends out sound waves that bounce off people and objects in the room and then returns them to the switch. 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. If the sensor doesn’t recognize any changes over a certain length of time, it turns off the light. - **A passive sensor** detects heat given off by people and animals. If the sensor detects heat, it triggers the switch to turn on. If the sensor detects no body heat after a certain amount of time, it triggers the switch to turn off. To avoid accidental triggers from sunlight, the sensor’s sensitivity allows it to ignore gradual changes in heat. ### Extra Functions Motion sensor light switches include extra functions that allow the user to customize how they work. - **Daylight sensing:** Sensors assess the level of ambient lighting in the room and turn the lights on or off based on that level. If the sensor detects that the room is already bright enough, it will not turn on the lights. Daylight sensors have dials that let the user customize the sensitivity. - **Dimming:** Most motion sensor lights do not function as dimmers. There are, however, specialty models with dimmer capability. These switches feature a motion detector and a paddle switch that controls the dimming. - **Motion sensitivity:** Many motion sensor light switches offer sensitivity settings that permit the user to fine-tune the level of movement that triggers the light. - **Smart technology:** [Smart motion sensor light switches]() connect to a home’s smart hub, allowing the user to control the lights, create lighting scenes, program schedules, and change the sensitivity settings via a smartphone. ### Light Bulb Compatibility Motion sensor light switches can handle a significant amount of wattage. Most have a capacity of up to 500 watts for incandescent bulbs and 250 watts for LED and CFL bulbs, which is far greater than any individual light bulb. This may be a vital feature to consider if the switch operates a light fixture that uses multiple light bulbs. A kitchen light fixture that uses six 60-watt incandescent bulbs, for example, would require a light switch with a capacity greater than 360 watts. ### Wiring and Installation When taking the proper safety precautions, replacing a standard light switch with a motion sensor light switch is a project most DIYers can complete in less than 30 minutes. No special tools are required, although it’s a good idea to purchase a voltage detector—an inexpensive device that detects if a wire is live—for safety purposes. Most [light switch installations]() require only a standard Phillips-head screwdriver and a flathead screwdriver. Single-pole light switches have two wires and a ground wire. A hot wire, which comes from the home’s power source, connects to one of the switch’s terminals. A second wire, which goes to the light fixture, connects to the other terminal. A copper wire that serves as the grounding wire connects to a third terminal, which prevents the light switch from shorting out during a power surge. ## Our Top Picks These top picks narrow the field to some of the best motion sensor switches on the market. These switches feature numerous settings that allow the user to fine-tune sensitivity, adjust vacancy and occupancy settings, and set time delays. Some are compatible with three-way switches and dimmers, while others can connect to [smart devices.]() An inaccurate motion sensor light either leaves a person in the dark or leaves an unoccupied room fully lit.
