What is a Motion Sensor?
Motion sensor is a device that recognizes the movement of objects around it, such as humans, animals or solid objects. They are usually used in security systems, lighting and automation to create a response when detecting movement. Motion sensors are available in different technologies and are designed for different work.
How does the motion sensor work?
All motion sensors have a two -phase mechanism: motion detection and reaction. They detect movements in a specific area and begin predetermined reactions such as lighting lights or sounding alarm. However, detection tools from one motion sensor are different. Each type also has features that make it more suitable for different environments.
Types of motor sensors
Active motor sensors
How the Active Motion Sensors works is that it constantly sends ultrasound waves out and returns to the sensor again. This pattern is repeated uniformly until one is impaired by a factor like a person's steps, at which time the alarm sensor sounds. This sensor is also called a radar -based motion sensor.
Passive motor sensors
The sensor is divided into two categories, both of which are suitable for home and workplace.
Video motor sensor
The sensor is functioning through laser beams and. When a movement passes through the light of the lasers, the change of light is changed and the alarm alerts.
Passive sensor
In this sensor, the infrared energy is released out, and when the waves hit the animal or humans, it returns to the sensor as thermal energy and the alarm sounds. The feature of this sensor can be the ability to adapt to ambient temperature and sunrise and sunset.
The benefits of motor sensor
Energy -saving
The first advantage of the sensor is the ability to adjust the duration of the lights and save the power consumption when coordinating with the corridor. A motion sensor can help light smart lights and switches, speakers and TVs when a room is empty for a long time or at a specific time. Contact sensors on doors and windows can signal the intelligent thermostat to turn off when opening and turn on if closed. When a room temperature is too hot, a temperature sensor can reduce the temperature.
High level of security
The thieves cannot disable the sensor, as soon as the thief is approached, the alarm sounds and the thieves are unable to steal.
Small dimensions and wide range of lens
In general, one of the best advantages of these sensors is their small size and wide lens that has greatly attracted its customer satisfaction.
Durability
Generally, motor sensor has a long life span. And they are a rational and profitable action given their benefits and applications.
appropriate replacement of power key and timer Easy installation and easy displacement capability due to being wireless
