ToF range sensor offers multi-object detection and accurate range measurements

Mouser now offers the ICU-20201 ToF range sensor from TDK InvenSense. The device is a miniature, ultra-low power (1.8V), long-range ultrasonic sensor based on patented compressed high-intensity radar pulse MEMS technology, perfect for smart door lock wake-on-approach, obstacle avoidance, wall following, parking lot sensors for vehicle counting, and ground-level measurement in drones.

The ToF range sensor provides multi-object detection and accurate range measurements to targets up to 5m and can function in any lighting condition, including full sunlight to complete darkness. Featuring an integrated 85kHz PMUT with a second-generation ultra-low power SoC, this reflowable package also offers a customisable FOV up to 180° and a single sound port for receiving and transmitting.

The EV_ICU-20201-00 evaluation board supports the sensor. The board includes the ICU-2021 ultrasonic sensor device, support circuitry, test points and a 12-pin 0.5mm pitch FFC connector. This board needs an acoustic housing to interface with the IC.

Also, the company stocks the DK-x0201 development kit for the ICU-2021 Ultrasonic ToF sensor. This kit includes a development host board providing the Microchip Technology SAMG55 microcontroller, a daughter evaluation board, and a target board with a pre-mounted ICU-2021 sensor. The kit facilitates rapid evaluation and development of the ICU-2021 sensor when connected to a PC running the downloadable GUI-based development software and embedded drivers.
