TDK InvenSense’s ultrasonic ToF range sensor for ultra-long-range applications
Mouser is now stocking the ICU-30201 ultrasonic time-of-flight (ToF) range sensor from TDK InvenSense. The ICU-30201 is a high-performance ToF sensor for ultra-long-range applications, measuring distances from 30 cm to 9.5 m with millimeter accuracy. The sensor enhances contextual awareness and reliability in diverse environments, including smart homes, robotics, and obstacle avoidance.
The TDK InvenSense ICU-30201 ultrasonic ToF range Sensor delivers accurate measurements in any lighting condition, from full sunlight to complete darkness, and can detect optically transparent surfaces such as glass and clear plastics. The ICU-30201 supports multi-object detection with a customisable field-of-view (FOV) up to 180°. The sensor also features a 53 kHz piezoelectric micro machined ultrasonic transducer (PMUT) — a second-generation ultra-low power System-on-Chip (SoC) — and a 40 MHz integrated CPU for on-chip algorithms including range finding, human presence, and wake-on approach.
The ICU-30201 sensor offers a sample rate of 75 samples per second at two meters and 18 samples per second at nine meters. With ultra-low power consumption (22µA to 318µA depending on the number of samples per second), the ICU-30201 helps extend battery life in devices including smart speakers, meeting room devices, and smart door locks. A single bottom port package for receiving and transmitting allows for easy mechanical integration. The ICU-30201 sensor comes in a compact 5.17 × 2.68 × 0.9 mm LGA package and includes an integrated digital signal processor (DSP). The sensor is compatible with standard surface mount device (SMD) reflow and has an operating temperature range of -40°C to +85°C.
