Guide to buying a motion sensor


In order to acquire a good device with a motion sensor, it is necessary to first consider what you are going to need it for, so that you can invest your money in a product that is really useful and practical to complement your comfort, either at home or in the office.

Shopping guide


Type of device

The first thing to consider in this guide to buying the best motion sensor is the type of device. As you know, motion sensors have obtained an increasingly compact and discreet size over time, so that it can be integrated into other equipment.

In this case, you should consider the type, since the market offers you multiple accessories, devices, and even household appliances that work with motion sensors.

For example, if you want to have a lighting system that can be turned on without you having to flip a switch, you might consider lamps with motion sensors. These can be found in all kinds of designs, shapes and sizes so you can choose the one that suits you best.

For security, you might also consider motion-activated cameras or alarm systems so you can call the police or alert someone before an unknown individual gets too close to your property.

Those mentioned are just a few options with sensors, but you should know that there are many more alternatives in which you can find one, so you will have to clearly know what you need it for and then choose the most appropriate one.

team design

Regardless of what type of device you have chosen that is equipped with a motion sensor, it is very important that you consider its design. A comparison of motion sensors indicates that details such as the size of the device, its weight, material installation requirements, among many other aspects, must be analyzed.

Generally, when it comes to lighting systems, we recommend you consider waterproof ones in case you want to install the system outside. If it is an alarm, the same recommendation also applies to prevent elements of the weather from damaging the equipment.

In these cases, we also recommend that it be a model with a discreet design so that you can hide it if you wish or so that outsiders cannot notice its presence.

Manufacturing materials

You cannot forget the manufacturing materials used in the sensor or in the equipment that contains it. This may affect how much it costs, but it’s best to have a rugged device, which will prevent you from having to replace it anytime soon. In addition, it is also convenient to analyze the capacity of the sensor, which we will study later.

If you want to acquire a model that is economical, you have many options available, since, as mentioned, there are a large number of devices that work with sensors, try to balance the greatest number of advantages for the cost that you are willing to pay.

In general, these sensors offer a certain degree of protection and although they work with delicate components, most manufacturers try to offer them a protective casing that will prevent them from being affected by external agents.

sensor sensitivity

Another aspect that we advise you to consider carefully is the capacity of the sensor. These components are mainly responsible for activating a certain system when its sensors detect the presence of movement in front of it. Therefore, when you are going to choose one for your home, you should consider how far the equipment can detect. This way the chosen system will have enough time to react to the sensor command and activate properly.


If you have decided to buy a motion sensor to adapt it to a system you already have at home, the most essential thing to analyze is the compatibility of the component with your equipment. This can be verified according to the indications of the manufacturer of your device, as well as those specified for the sensor.

If you have doubts about it, the most convenient thing would be to consult with a specialist technician, who can answer your questions so that you do not end up wasting your money.

possible functions

Lastly, you may want to consider the features that a certain motion sensor offers you. Because this component is so versatile and has been able to adapt to so many pieces of equipment, very interesting and practical functions have also been developed to carry out its main work.

Depending on the device you have purchased, you will be able to enjoy actions parallel to those of simply turning a system off or on. Some motion sensors can be adjusted based on detection distance, as well as trigger the main unit with custom settings based on information received by the sensors.

Frequently asked questions

Q1: How to use a motion sensor?

Depending on the model of motion sensor you have purchased, you will have to install it or integrate it into the system of your interest.

If it is a spotlight, you will only have to place it in the socket entrance on your ceiling or wall and turn clockwise until it is firm. Remember to adjust the detection and brightness parameters.

In the case of a sensor to integrate, you must have knowledge in electronics, since with these sensors a bridge must be made between the main wiring of the system and that of the sensor, so that it can be activated when the device is activated.

Q2: How to connect a three-wire motion sensor?

To use a three-wire motion sensor you must first identify them. Manufacturers typically employ three colors for them: black or brown, blue, and red. The black wire is the line wire, the blue wire is the neutral wire, and the red wire is the return wire.

To connect the sensor to your lighting, alarm or opening system, you must connect the line cable and the neutral cable to the sensor input, so that the internal circuit of the system can be activated.

On the other hand, the return cable must be anchored to the sensor’s voltage output and connected to the system of interest, so that it can be activated upon receiving the detection. In addition to this, you will also need to connect a second end of the neutral wire to the system for circuit stability.

Q3: How to make a motion sensor alarm?

If you have knowledge of DIY and you are interested in making your own alarm system with a motion detection sensor at home, we advise you to purchase each device separately and then make a bridge between them, so that one can activate the other.

As mentioned in another answer, you must work with a sensor that allows the use of the three basic cables: neutral, line and return, which you must implement in the appropriate position next to the alarm system. As with a lighting one, the alarm will be activated when the motion sensor that you have integrated into its electronic circuit is triggered.

Q4: How does a motion sensor for lighting work?

Motion sensors, whether for lighting, security or any other purpose, work basically the same way: with infrared radiation.

 This type of radiation is capable of detecting the presence of heat in a room and the sensors are equipped with systems that, by detecting the change in radiation received, can activate the necessary components that send the order to the main system to turn on.

Therefore, when you walk into a room that has a motion-sensing spotlight, it can turn on simply because the human body naturally emits radiation and changes the range detected by the equipment.


Q5: How to connect a motion sensor to a switch?

If you need to connect a new motion sensor to the main light switch in your entryway, for example, the procedure and steps to follow are to work with the three wires that come with these sensors.

Similarly, you will have to interrupt the power supply for safety. Disconnect the cables that go directly to the switch of your interest and make the bridge using the cables of the motion sensor. Then put everything back in its place, integrating the sensor in the location you want keeping the connection and you’re done.

Q6: What is the motion sensor for?

Motion sensors are very useful devices that can both save labor and increase safety and comfort. These teams work with detectors that can be of different types: presence, movement, radiation, temperature, video, sound, vibrations, etc.

In general, domestic models are used to activate lighting systems when passing through a threshold or a corridor, thus avoiding having to search for the switch in the dark.

They can also be integrated into alarm systems, which will be activated when they detect the presence of outsiders too close to your property, so that they know that you are aware and this will dissuade them from leaving or, on the other hand, alert your neighbors.

Its applications are quite extensive, but it could be summed up to the fact that a motion sensor is capable of activating an external system through other types of interactions.

Q7: How to regulate a motion sensor?

This will depend on the type of motion sensor you have. In general, consumer models, which have integrated adjustment systems, have dials or buttons that allow you to change parameters such as detection distance, range, angle, among others.

Q8: How to install a motion sensor to a lamp?

To mount it, you will need to take the wires from the motion sensor and connect the return wire to the lamp along with the neutral wire. Then, install the phase cable in the positive socket of the outlet and the other end of the neutral cable to the negative socket, and then finish connecting a third neutral point to the sensor output.
