What are motion sensors?

Motion detectors are electronic devices equipped with sensors that respond to physical movements. They are generally connected to other security systems, closed television circuits, or lighting or ventilation systems that are activated when someone accesses the area covered by the sensor.

Motion sensors are present on a wide variety of objects, for example, on shop doors, allowing them to open automatically when our presence is detected. Although the most common use for this type of sensor is still that of security as part of an alarm system or a closed circuit of cameras.

What are the uses of motion sensors?

Motion sensors are commonly used for lighting common areas such as entrances and hallways. They are also often connected to ventilation systems, for example in public restrooms in restaurants. These activate the extraction systems by sensing the presence of a person near their area.

It is also normal to find these detection systems on automatic doors and in some elevators. Their function here is to open them when they notice the proximity of a presence. Of course, we cannot fail to mention its uses in the security and surveillance industry, either alone or as part of a more complex alarm system.

What types of motion sensors are there?

Motion sensors are an essential part of most alarm systems that you can find installed in homes. They are actually an essential part of the most advanced home automation equipment and can be found installed in windows or in sophisticated lighting set for a garden.

These detectors work differently depending on the type of sensor we are referring to. So that you understand how they work perfectly, we have prepared the following list in which we explain the different types of motion sensors that exist on the market:

Type of detectorSensor typeCommon usesCharacteristics
Passive Motion Sensor (PIR)Works with infrared sensors.It is the most used in domestic alarms.Detects changes in temperature and movement.Detects energy variations in the corresponding space.
Microwave movementActive sensors.vigilance.It emits pulses through the so-called “Doopler” effect. Waves bounce off the surface and detect changes.
By ultrasoundActive sensors.vigilance.They emit pulses of ultrasound.
By vibrationActive sensors.vigilance.They detect vibrations on the surfaces on which they are placed.
DualDual sensors.Home automation.vigilance.They combine passive and active receivers.They have greater reliability in the face of false alarms.
ReflectiveActive sensors.vigilance.They emit a beam of LED light that joins the emitter and receiver. If a body obstructs the beam, the alarm sounds.
ContactActive sensors.vigilance.They’re the cheapest thing.They fire when the door or window to which they are attached is opened.

What is the twilight sensor?

When it comes to motion sensors, these often include twilight sensor functions. However, the twilight sensor should not be confused with the motion sensor, as their function and purpose are different. The twilight sensor or light sensor detects an excess or defect of illumination within a space causing this to be activated.

These sensors must be programmed and calibrated. When activated, they open or close the circuit to which they are connected to turn off or on the lights of the facilities. They are a good option for saving and energy efficiency. If you’ve ever wondered how your street lights are turned on, the answer is: via a twilight sensor.

What are the advantages of using motion sensors?

Now that you know what a motion sensor is and you know the different uses and types of sensors that exist in the market, the next question may be: what advantages do motion sensors provide us as users? Here are some of the advantages that sensors provide in a home system:

  • The widespread use of sensors in alarm systems makes them an essential element for the security of your home. Regardless of the type of sensor you choose, its use guarantees greater peace of mind when detecting any presence.
  • Energy-saving. The fact of including one in your home lighting system will make forgetting to turn off the lights no longer a problem.
  • Economic factor. It is always an important reason for deciding to buy a product. The use of these sensors is not expensive, if you add what it compensates for by preventing theft and saving on electricity, this becomes a great advantage.
  • Tranquility. Your home will be safe from any unexpected movement and the lights in your house will turn on and off without having to press a switch.

What are the differences between a presence detector and a motion sensor?

Motion sensors are characterized by having a much lower sensitivity, they detect the heat given off by people or moving objects through infrared, activating or deactivating depending on the footprint or thermal image they receive. Presence detectors work in a similar way, but they capture information continuously.

Based on these differences, the applications of both devices will be diverse. While motion detectors are especially suitable for passageways such as entrances, stairways, or corridors, presence detectors are used in interior areas or areas where people stay for a long period of time, such as offices.

Where should I put the motion sensors inside?

Motion sensors are very easy to install and offer a host of benefits. As you have already seen, they will allow you to save on your electricity bill or they will keep your home protected. Unlike connected systems, these devices help us to illuminate busy places, although they also allow the use of air conditioners and extractors.

When installing a motion detector indoors you should take into account:

  • The passage areas of the house are strategic points for the placement of motion sensors. Doors, hallways, or stairs are a good option. In general, all those places of obligatory passage to move around the property should be covered with a detector.
  • Try not to place the sensors next to windows or air conditioners. Strong wind, moving curtains, or rain could cause errors.
  • Make sure there are no consistent obstacles (furniture) interfering with the sensor coverage.
  • Remember that if you have pets at home, you must place sensors that are immune to the presence of animals.

Where should I put the motion sensors outside?

When installing motion sensors outdoors we must take into account some factors. For example, the measurement range that your device offers or if you can install it in corners, ceilings, or walls. In any case, you should know that the sensor is more sensitive to the movement that crosses the detection beam than to the movement that follows its same path.

Here are some tips for installing your motion sensor in outdoor areas:

  • Locate the motion sensors in hard-to-reach areas (heights, columns, angles to the roof) to prevent them from damaging or sabotaging the system.
  • Take into account the range of the sensors and do not exceed the installation height, as it will lose effectiveness.
  • The front door is a key point in any property. Make sure you install a motion sensor there. You can improve the level of protection if you also have a video surveillance camera system.
  • Do not lose sight of factors such as exposure to light or heat to which the sensor is going to be subjected because, depending on the model, it can interfere with its correct operation.
  • If you install motion sensors in garden areas, be aware that the presence of vermin (mice, snakes, or lizards) can lead to a false alarm. Calibrate the device to avoid detection errors.

Purchase criteria

You have already seen that motion sensors are present in a wide variety of situations. Security systems, doors to shopping centers, and even in public bathrooms or offices. As you can see, they are very useful and easy to install systems that will allow you to save money and feel safe. So that you can choose better, below, we provide you with the criteria that you must take into account when choosing your sensor:


The most common and cheapest motion sensors are PIRs. These devices are activated by infrared and, connected to a lighting system, allow the lights to be turned on or off by presence. This type of detectors will remain active as long as there is a movement of people in the area.

Those of presence is more sensitive and register minimal movements, for example, those made while sitting. Some have built-in lamps that work through built-in solar panels, these use a clean energy source and allow greater savings, but they can only be used outdoors.

Handling and design

The handling of the motion sensors does not represent any complexity, you simply have to move within their detection range for them to work. However, it is important to buy a model with well-described functions to avoid mistakes and in which the control buttons are clearly distinguishable.

Design and structure also play a very important role. This is the factor that will allow you to differentiate the control buttons or install the detector in a corner, a ceiling, or a wall. The design will also allow you to combine the device with your decoration and place it in strategic places that are more efficient.

Reaction time

Like all sensor-powered equipment, motion detectors have a reaction time. This is the time it takes to illuminate from the moment it detects some type of activity, and also the time in which it turns off once it stops registering movement.

As always, the more sensitive sensors will have a better reaction time. This factor can be decisive, especially if your sensor is installed in an area that requires a lot of light, such as a staircase. The reaction time, as well as the consumption time, are detailed in the specifications of each manufacturer.

Lighting type

You should not forget to assess the lighting capacity, in the same way, that you would if it were an LED bulb or a lighting lamp. If the detector incorporates the lighting option, look at the type of light it offers, the technology it uses to emit light, its hue, beam, and brightness, and if these are adapted to your space.

Detection distance and angle

The range that the device has to detect movements and the level of reach of the light that it projects when it is turned on are other important factors, it will depend on whether it can be placed in large rooms or only in smaller ones. The detection range will also be essential to know if you can use it outdoors.

And the same will happen with the detection angle. Motion sensors, as a general rule, detect movements that cross their beam of light but suffer from movements that follow the same direction. Look for sensors with wide angles, which you can place in corners where it is more difficult to follow the direction of the beam.

Autonomy and battery

An indicator of the quality of the motion sensor is the level of energy that the device has to operate for a long time. The more hours it lasts, the better. It is important that you have a battery with long life and if it is removable that it is easy to replace or that it is rechargeable.

Most modern and quality motion sensors are not battery-powered but are connected to electrical current. In this case, you should look at their consumption and whether or not it adapts to your needs and the electrical installation of your home. If you buy a sensor with too much voltage, you could have problems.


Many motion sensors require somewhat complex installation. In the case of devices installed or placed in sockets, they will require some knowledge of electricity. In most cases, to install a motion sensor you will need to hire an electrician to make the necessary connections.


They open the doors of shops and shopping centers for you, turn on the lights for you in public spaces and illuminate the streets when night falls. All this without being seen is how useful and discreet the motion sensors are. As if that were not enough, installing one of these devices in your home will save you money on your electricity bill.

Remember that before choosing the best motion sensor for your home or business, you must take into account certain factors such as ease of installation, the autonomy of its batteries, the distance, and angle of detection, or its reaction time. In this article, we have explained everything you need to know to make a good purchase. Now it’s up to you to make the best choice.
