HB102|AUDIOWELL MEMS Ultrasonic Sensor‌

MEMS Ultrasonic Sensor‌Model：HB102

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.

Products info

The MEMS ultrasonic sensor with a resonance frequency of 40 kHz has low attenuation in common media (such as air) and a moderate wavelength (approximately 8.8 mm).

Features

- Ultra-small size: 5.7 x 5.2 x 1.4 mm

- Easy to integrate into various scenarios: LGA packaging, no separate soldering required

- Wide field of view: A single sensor chip can achieve a 160° field of view

- High reliability: Strong light, moisture, smoke, etc. will not interfere with detection accuracy
