![]() ![]() Most motion sensors allow you to configure sensitivity, meaning it won’t trigger if the distance to the object is too far. ![]() The sensor determines the distance between itself and the target by measuring the time between sending and receiving the signal. A transducer within the sensor acts as a waypoint for the signal-it sends the pulse and receives the echo. These waves bounce off objects in the immediate vicinity and return to the motion sensor. There are two widely used types of motion sensors: active ultrasonic and passive infrared (PIR).Īctive ultrasonic sensors and passive infrared sensors are the two most common motion sensor technologies, both of which are known for their accuracy and reliability.Īctive ultrasonic sensors emit ultrasonic sound waves at a frequency above the range of human hearing.
