Chirp Microsystem Made The Smallest And Most Accurate Ultrasonic Time-of-Flight Sensors

https://www.electronics-lab.com/70595-2/

Recently Californian startup Chirp Microsystems officially announced two discrete ultrasonic Time-of-Flight (ToF) sensors, the CH-101 and CH-201, with maximum sensing ranges of 1m and 5m, respectively. Both chips have a 3.5×3.5mm package and they are powered by same ASIC or application-specific integrated circuit for signal processing. To achieve different sensing ranges, the Piezoelectric Micro-machined Ultrasonic Transducers (PMUT), the […]
