ultrasonic distance meter
A ultrasonic distance meter, the sophisticated equipment, uses high frequency ultrasound in order to detect whereabouts then give answers through visual or aural output modalities. Its functions include calculating the distance between device and an object--usually within a range of a few cm to several meters depending on model. With a microcontroller unit and ultrasonic transducer to send/receive soundwaves, and advanced algorithms that even consider temperature and humidity, the technological features of the ultrasonic distance meter give him superior measurement accuracy.Used in construction, industrial automation and robotics for obstacle detection plus map data generation. The interface is user-friendly; it also s small enough to provide a "must-have" utility for both professional and amateur users.
