HB101|AUDIOWELL MEMS Ultrasonic Sensor‌

MEMS Ultrasonic Sensor‌Model：HB101

MEMS ultrasonic sensor is a new type of sensor that combines microelectromechanical system (MEMS) technology with ultrasonic technology. It uses micro-machining processes to convert electrical energy into acoustic energy and vice versa, offering features such as miniaturisation and low power consumption. This makes it a flexible solution for both consumer electronics and industrial applications.
