How Do Motion Sensors Work | Where To Place Them

Most people know that motion sensors are used in things like automatic lights, but few people know how they actually work. In this blog post, we're going to take a look at how motion sensors work and where the best places to put them are.


What Is a Smart Motion Sensor? 

Smart motion sensors are ways of detecting movement in and around your property, which then has an impact on your home's functionality. For example, a smart motion sensor might turn the lights on automatically when you enter a room. They may also send you an alert if an intruder is attempting to break into your house. The objective of motion sensors is to offer security and help your home operate more smoothly and efficiently, in the end.


How Do Smart Motion Sensor Work? 

The most popular smart motion sensors utilise passive infrared (PIR) technology. PIR detectors detect infrared radiation emitted by humans and other animals as body heat. As a result, when the temperature rises suddenly, your gadget will notice the change and notify your control panel.

It is worth noting that PIR sensors can be set to ignore small fluctuations in temperature; therefore you don't have to worry about your pets setting off alarms inadvertently.

There are also microwave motion sensors. These emit radio waves in aspecific range and return them back to the sensor after they have bounced off the moving thing (or person).

There are also motion sensors that employ both of these technologies, but they are not as prevalent.


The Many Types of Smart Sensors  

  • Temperature sensors - which have smart thermostats tomonitor temperature throughout your house
  • Lightsensors - it reads the amount ofsunlight in your home, and allows you to automate certain lighting features
  • Smokedetectors - to detect fire outbreaks in your home
  • Waterleak sensors - to detect leaks in your home
  • Airquality sensors - todetect contaminants in your home


Ways To Use Motion Sensors In Your Home 

(1) Protect Your Entryways 

One of the most obvious ways to use a motion sensor is to protect your home’s entryways. By placing a sensor near your front door, you can be alerted whenever someone approaches, whether it’s a family member coming home or an intruder. You can also set up your system so that the lights turn on automatically when the sensor is triggered, making it easier to see who’s there and deterring burglars.

(2) Detect Leaks 

Sensors may be used to detect a variety of water leaks and rapid changes in water temperature. This aids in the prevention of flooding and other forms of water damage in your property. To get the most out of your sensors, position thembeneath dishwashers, sinks, and any other devices that are susceptible to leak. Then connect your smart device to the sensors to receive alerts about leaks or other water concerns as soon as they are detected.

(3) Light Control 

Ina ddition to turning lights on and off, some home automation systems allow you to dim and brighten them as well. This can help you save energy and create the perfect ambiance for any occasion. You can also set your lights to turn on and off at specific times or when certain conditions are met, such as when someone enters the room.

(4) Monitor Areas In Your Home 

In addition to monitoring activity at your home’s entrances, you can also use motion sensors to keep an eye on activity in other rooms. If you have valuable items in a room, you can place a sensor there to alert you if anyone goes near it. These sensors can also be helpful in keeping an eye on children or elderly family members who may need assistance.


Where Can You Place Your Motion Sensors 

(1) Near Your Valuables 

If an intruder moves or tries to steal your valuable things, a motion detector near or behind them will trigger the alarm.

(2) Above Doorways - Entry Points 

Motion sensors placed above doorways hide them from view while making it nearly impossible for intruders to enter without setting off the alarm.

(3) Corners 

Installing a motion sensor in the corner of your room will provide your device with the most comprehensive view of the area beneath. Just make sure the sensor is pointed at the door and there are no obstacles in its path.

(4) "Blind Spots" 

Installing a motion sensor in a "blind spot" - an area where the view is obstructed by your security camera, or in areas in the home where view is limited can be wise.


In conclusion, proper placement of your home security devices is critical to ensuring the safety of your home. By following these simple tips, you can be sure that your home is as secure as possible.
