TDK InvenSense Chirp Products are a family of miniature and ultra-low power ultrasonic Time-of-Flight (ToF) range sensors and modules based on MEMS technology. These sensors feature a system-in-package that integrates a Piezoelectric Micromachined Ultrasonic Transducer (PMUT) with an ultra-low-power System on Chip (SoC) in a miniature, reflowable package. The CH101 and the CH201 sensors can detect multiple objects, work in any lighting conditions, including full sunlight, and provide millimeter-accurate range measurements. The Chirp family products include ultrasonic sensor modules, development kits, and software, depending on the application requirements.
