Time-of-flight sensor ranges up to 5 metres

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

This ToF range sensor offers multi-object detection and accurate range measurements to targets up to 5 metres and can operate in any lighting condition, including full sunlight to complete darkness.

Featuring an integrated 85 kHz piezoelectric, micromachined ultrasonic transducer (PMUT) with a 2^nd generation ultra-low power System on Chip (SoC), this reflowable package also offers a customizable field-of-view (FOV) up to 180° and a single sound port for receiving and transmitting.

The sensor is supported by the EV ICU-20201-00 evaluation board.

It includes the ICU-2021 ultrasonic sensor device, support circuitry, test points and a 12-pin 0.5 mm pitch flat flex cable (FFC) connector. This board requires an acoustic housing to interface with the IC.

Additionally, Mouser stocks the DK-x0201 development kit for the ICU-2021 Ultrasonic Time-of-Flight (ToF) sensor. This kit includes a development host board featuring the Microchip Technology SAMG55 microcontroller, a daughter evaluation board, and a target board with a pre-mounted ICU-2021 sensor.

The kit enables rapid evaluation and development of the ICU-2021 sensor when connected to a PC running the downloadable GUI-based development software and embedded drivers.
