High-Performance Ultra-Compact Ultrasonic Time‑of‑Flight Sensor for Long-Range Applications


The ICU-20201 is a high-performance ultrasonic Time-of-Flight sensor that is ideal for measuring the range of objects between 20cm and 5m, and offers a customizable field-of-view of up to 180º. It has a sample rate of 150 samples per second at 1 meter, and 32 samples per second at 5 meters. It comes in a 3.5 × 3.5 × 1.26 mm LGA package, and includes an integrated DSP for signal processing.

The ICU-20201 extends battery life via its ultra-low power consumption (26µA – 300µA depending on the number of samples per second), and is highly flexible thanks to a large amount of embedded program and data memory. It is also available in a module.
