Motion sensors are specialized electronic devices that record movement and transmit information to the control system. Depending on the type of sensor, they can detect movement by measuring temperature change, light reflection, sound wave or mechanical movement. Here is the ranking of the best motion sensors.

How do motion sensors work?
Motion sensors are extremely useful electronic devices that can detect the movement of objects or people in their surroundings. Depending on the type, the devices are based on motion detection via infrared or detection of changes in the electromagnetic field.
A motion sensor usually consists of two basic elements: a detector and an electronic system. The detector is able to detect movement and convert it into an electrical signal, which is then sent to the electronic system. Depending on the signal, the electronic system can trigger an alarm, lighting or other motion-controlled devices. Our wholesaler has an extremely diverse range of motion sensors. Below we present a list of the 5 most frequently purchased motion sensors that were most popular among our customers.
Infrared motion sensor IP44 Opal
This is an excellent option for people looking for a high-quality motion sensor at an affordable price. This sensor uses infrared radiation to detect movement in its field of view. When a body with a temperature different from the surroundings moves in the sensor's field of view, the amount of infrared radiation reaching the detection elements changes.
The presented sensor has a maximum range of 12 meters at a temperature of up to 24 degrees Celsius. The delay is +/-3 seconds. The device can operate at temperatures from -35 to +50 degrees Celsius. It is made of thermoplastic. It can be installed using the surface-mounting technique. The viewing angle is 180 degrees.
IP44 Niko impulse motion sensor
Pulse sensors use high-frequency electromagnetic waves instead of infrared radiation. These types of sensors are often used in alarm systems, motion-sensor lighting, and industrial automation because they are able to detect movement through walls and obstacles, something that is difficult to achieve with infrared sensors. The presented model has a range of 12 meters and a detection angle of 200 degrees. It also has a mounting socket for quick and easy connection. It can operate at temperatures from -20 to +50 degrees Celsius.
IP44 BEG motion sensor
The presented sensor has an adjustable head and a detection angle of 140 degrees. It can be mounted in a standard flush-mounted box. Additionally, its range is a maximum of 12 meters (lateral). This sensor can operate effectively at temperatures from -25 to +50 degrees Celsius. The device casing is made of polycarbonate, which is resistant to UV radiation.
Niko IP55 motion sensor for large areas
A premium sensor that is distinguished from previous proposals by a higher IP coefficient, wider detection angle and better range. The IP coefficient is as much as 55, the detection angle is up to 200 degrees, and the maximum range is 30 meters. The device also has a remote control function, which is an important convenience. The presented sensor operates in pulse mode and can operate at temperatures from -20 to +55 degrees Celsius.
Microwave motion sensor with F&F IP40 presence sensor function
Another sensor worth recommending, which is additionally equipped with a special presence sensor function. The protection level here is IP40, the operating temperature is from -20 to +50 degrees Celsius, the detection angle is 360 degrees, and the range is up to 10 meters.
