Doors that open when you get close, lights that turn on when you enter a room or street lamps that illuminate the street you walk in when night falls.

No, it’s not magic, it’s just motion sensors. These electronic devices have sensors capable of detecting any type of movement or light change in the area in which they are installed.

But it’s not just about that; motion sensors can be installed together with a ventilation or security system to activate them as soon as they detect movement. It is very convenient for not having to turn on the switches every time.

Buying Guide to Select the Best Outdoor Motion Sensor

Many alarms and lighting systems work thanks to motion sensors. It is not uncommon to find them in hotel corridors or in restaurant bathrooms. They are very comfortable and help to reduce electricity consumption. To make a purchase with criteria, we will explain everything you need to know about it.

What Are Motion Sensors?

Motion sensors are electronic devices equipped with sensors that respond to physical movements. Generally, they are connected to other security systems, closed television circuits or lighting, and ventilation systems that are activated when you enter the affected area.

These devices are present in a wide variety of elements, such as the doors of shopping centers that open automatically, even if the most common use continues to be that of a security device, alarm, or closed circuit of cameras.

What Uses Can a Motion Sensor Have?

Motion sensors are commonly used for the lighting of common areas such as entrances and corridors, or in the ventilation systems of public restrooms in restaurants. These activate an extraction system as soon as movement is perceived in the covered area.

It is common to find them also in the automatic doors of the elevators, which, open as soon as someone approaches.

Obviously, the use made of it in the security and surveillance industry is not to be overlooked, both as a single unit and as part of a more complex alarm system.

What Is the Twilight Sensor?

Motion detectors often have twilight sensor functions. However, care must be taken not to confuse the latter with the actual motion sensor, since they have a different position and purpose. The twilight sensor, or light sensor, detects an excess or a defect in lighting in a particular area and thus activates.

These sensors must be programmed and calibrated. When they are activated, they open or close the circuit to which they are connected to turn the lights on or off.

This is definitely a good option for saving and energy efficiency. If you have sometimes wondered how the street lamps turn on, you now know that it is thanks to a twilight sensor.

What Is the Difference Between a Presence Detector and A Motion Sensor?

Motion sensors have a lower sensitivity, detect the heat dispersed by people, and moving objects through infrared, activating, or deactivating according to the thermal image they receive. Presence detectors work in a similar way, but by capturing the information continuously.

Starting from these differences, the applications of these devices vary. While motion sensors are indicated for passage areas such as entrances, stairs, or corridors, presence sensors are used in internal areas or where more people tend to stay for a long time, such as offices.

Where Should the Motion Sensors Be Placed Inside?

Motion sensors are elementary to install and offer a lot of benefits. As you have already read in this guide, they will allow you to save on the electricity bill and make your home safer.

Unlike connected systems, these devices help to illuminate occupied rooms and even allow you to use air conditioning and the ventilation system.

When installing an indoor motion sensor, you will need to consider several factors:

The passage areas of the house are strategic points for the location of the sensors. Doors, corridors, and stairs are excellent locations. In general, all the places where you have to pass by force to reach a room are perfect for placing sensors.

Try not to place sensors near windows or air conditioning. Strong wind, moving curtains, or rain may mistakenly activate the sensor.

Make sure there are no (moving) obstacles that could interfere with the area covered by the sensor.

Remember that if you have pets, you will have to choose sensors immune to the presence of animals.

Where Should the Motion Sensors Be Placed Outside?

When installing a motion sensor outdoors, you will need to consider several aspects. For example, the measuring range that the device offers or if you can place it in the corners, on the roofs, or on the walls.

In any case, you must know that the sensor is susceptible to the movements that cross the detector beam of its trajectory.

Below, we give you some tips to successfully install the motion sensor outdoors.

  1. Place the motion sensor in areas that are difficult to access. (heights, columns, corners with roof) to prevent the system from being damaged.
  2. Take into account the range of the sensor and do not place it too high, or it will not help.
  3. The entrance door is a crucial point in the installation. By positioning a motion sensor, you can make the entrance safer, especially if integrated with a video surveillance camera system.
  4. Do not neglect the exposure to light or heat to which the sensor is subjected, depending on the model, and these factors could interfere with the operation.
  5. If you install a motion sensor in the garden, consider the presence of several animals (mice, snakes, or lizards) that could cause a false alarm. Calibrate your device to avoid detection errors.

Purchase Criteria

Now you know that motion sensors are present in many situations: security systems, shopping center doors, and public toilets or offices.

As you can see, they are instrumental and easy to install and will allow you to save money and have more security. To help you choose the best, we have collected a series of criteria to evaluate.

  • Types
  • Use and design
  • Response time
  • Detection distance and angle
  • Autonomy and battery

Types

The most common and cheapest motion sensors are PIRs. These devices are activated with infrared and connected to a lighting system, and they allow you to switch lights on and off when they detect movement. This type of sensor remains active for the duration of the action.

Presence detectors are more sensitive and record minimal movements, for example, those that are done while sitting. Some have built-in lamps that work through built-in solar panels, so they use a clean source of energy and help save money. However, they can only be used outdoors.

Use and Design

Using a motion sensor is not complicated since it is enough to move within its range of action for it to work.

However, it is essential to choose a model with specific functions to avoid mistakes and that the buttons can be clearly distinguished. Design and structure play an equally fundamental role.

This is the aspect that will allow you to distinguish the buttons or install the sensor in a corner, on the roof, or on the walls. The design also allows you to combine the device with home decorations in order to optimize its functions fully.

Response Time

Like all sensor devices, motion detectors have a reaction time. This is the time that the sensor takes to turn on the light from the moment movement is detected, and it is also the time it takes to turn it off when it is no longer perceived.

As always, the most sensitive sensors will have a shorter reaction time. This factor is crucial, especially if you place it in a place that requires a lot of light, such as stairs. Information on reaction time, as well as on consumption, is provided by the manufacturer of each product.

Detection Distance and Angle

The range of the device for detecting movements and the range of light it projects when it is turned on are essential factors because the possibility of placing them in large or small rooms depends on them.

The detection range is also essential to know if you can use the sensor outdoors. The same is true for the detection angle.

The sensors generally detect the movements that pass through the light beam but have difficulty seeing those that follow the same direction.

Look for sensors that have a wide-angle, which you can place in areas where it is more difficult to follow the direction of the beam.

Autonomy and Battery

One of the indicators of the quality of a motion sensor is the autonomy of the device. The more hours it stays on, the better. It is also essential that it has a battery with extended useful life and, if it can be removed, it must be easy to replace or rechargeable.

Most modern quality sensors do not run on battery power but via connection to the mains.

In this case, you will have to take care of the energy consumption and whether it adapts to your needs and to the electricity grid of your home. If you buy a detector with a too high voltage, you may have some problems.

Conclusions

They open the doors for you, turn on the light, and illuminate the street. All this without being noticed so as to be useful and discreet. And if that isn’t enough, installing a motion sensor will save you a lot on your electricity bill.

Remember that before choosing a sensor for the home or for your shop, you will have to evaluate factors such as ease of installation, battery autonomy, distance, and angle of detection or reaction time.

In this article we have given you all the information you need to buy the perfect product, now it’s your turn!
