TDK InvenSense ICU-30201 Ultrasonic Time-of-Flight Range Sensor
TDK InvenSense ICU-30201 Ultrasonic Time-of-Flight Range Sensor is a high-performance, ultra-compact solution designed for ultra-long-range applications. The TDK InvenSense ICU-30201 measures distances from 30cm to 9.5m with millimeter accuracy, regardless of lighting conditions or target transparency. Featuring a customizable field-of-view of up to 180°, this sensor supports multi-object detection and operates with ultra-low power consumption, extending battery life. The sensor integrates a 53kHz Piezoelectric Micromachined Ultrasonic Transducer (PMUT) and a second-generation ultra-low power System-on-Chip (SoC) in a miniature, reflowable package. Ideal for smart homes, building automation, robotics, and obstacle avoidance, the ICU-30201 enhances contextual awareness and reliability in diverse environments.
