It comes complete with ultrasonic transmitter and receiver module. Ultra sonic sensor The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors ...

A small electromagnetic emission experimental teaching system based on STM32F103 microcontroller and ultrasonic sensor is designed. Through electromagnetic launch theory analysis, the structure ...

We propose a nanocrystalline porous silicon (nc-PS) ultrasonic transmitter with a variable directional pattern. The directional pattern is realized by using an interference effect. An ultrasonic wave ...
