MEMS Ultrasonic Sensor
Product model: PU0005
PU0005 is a highly integrated ultrasonic sensing SoC (System on Chip). The chip integrates a PUMT micromachined ultrasonic transducer, signal amplification and processing module, ADC data acquisition module, MCU core, multi-protocol communication interfaces (SPI/UART/I2C), and GPIO modules. It can operate as a slave device communicating directly with a host/master controller, or as a host device to directly control and drive various peripherals. Designed for smart home application scenarios, it is ideal for range measurement, obstacle avoidance, proximity sensing, and automatic switches.
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
