MEMS Ultrasonic Sensor
Product model: AU0012
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.
Product Features
- MEMS ultrasonic sensor with a resonance frequency of 450 kHz, featuring a high frequency that results in an extremely short wavelength (approximately 3.3 mm in water), enabling easier focusing of the sound beam.
- - Can be packaged using SMT technology, allowing direct reflow mounting on a PCB without individual soldering
- - Compact size, suitable for a variety of application scenarios
- - High sensitivity for superior detection performance
- - Resistant to strong light interference with high stability
