What is a PIR Motion Sensor?<\/h2>
A PIR(passive infrared) motion sensor is an electronic sensor that passively measures infrared light emitted from objects in its field of view. <\/p>
As PIR motion sensors are widely used in PIR technology based motion detectors, the term PIR motion sensor<\/a> is commonly referred to as the motion sensor detector\/switch rather than the motion sensor electronic component itself.<\/p>

A home motion sensor<\/figcaption><\/figure><\/div> PIR motion sensors, in most cases, work as an automatic light switch that turns on the light when motion is detected and turns it off while you leave. Using a motion sensor light switch<\/a> can significantly save energy and electric bills while adding more comfort and convenience to your home life.<\/p>

Things to Consider When Choosing Home Motion Sensors<\/h2>
We listed some major factors to consider that can help homeowners to choose the ideal motion sensors for their homes<\/a>.<\/p>
Choose Functions that You Need<\/h3>
Motion sensors mainly include two working modes: the auto on\/auto off occupancy mode<\/a> and the manual on\/ auto off vacancy mode. <\/p>
Simply put:<\/p>
- Occupancy mode(auto on\/auto off) turns the light on and off automatically with more convenience. You don\u2019t have to mind about the lighting at all.<\/li>\n\n
- Vacancy mode(manual on\/auto off) requires you to manually turn on the light and automatically turn it off while you leave. Compared to occupancy mode, vacancy mode could save more energy and keep the lights always off with no light false-on caused by motions.<\/li><\/ul>

Occupancy Mode and Vacancy Mode<\/figcaption><\/figure><\/div> While most motion sensors offer an integrity that combines the two modes into one, allowing you to switch modes freely for different applications and scenarios. There are certain types of motion sensors that are labeled as either an occupancy sensor<\/a> or a vacancy sensor only, meaning the function is singular and cannot be changed. <\/p>
For home usage, there are certain places more suitable for occupancy modes like bathrooms<\/a> and garages. Places like master and kid bedrooms can be installed with vacancy sensors where you don\u2019t want the light to turn on while in a good sleeping.<\/p>
Or, simply choose a 2-in-1 motion sensor that you can change working mode any time you need. <\/p>
Mind the Installations <\/h3>
The installation is very easy. DIYers can replace and install motion sensors<\/a> with only a screwdriver in under 15 minutes. But before choosing your ideal motion sensors, take a look at your light switch wallbox to see if there is a neutral wire or not.<\/p>
