TDK Corporation announces the successful integrations of the InvenSense CH201 ultrasonic Time-of-Flight sensors into the Kaadas K9-F 3D Face Push-Pull WiFi smart door lock, enabling its face recognition functionality to automatically unlock for recognized users, which was recently launched into the consumer market.
- InvenSense sensor successfully deployed and integrated into the Kaadas K9-F 3D Face Push-Pull WiFi smart door lock
- The auto-wake function in the lock is powered by InvenSense SmartSonic™ CH201 Time-of-Flight sensors
- The CH201 MEMS sensor provides accurate range measurements and works in any lighting condition
InvenSense’s SmartSonic™ family of ultrasonic Time-of-Flight (ToF) sensors integrates a MEMS PMUT (Piezoelectric Micromachined Ultrasonic Transducer) with an ultra-low power SoC (System on Chip) in a miniature reflowable package. Based on ultrasonic pulse-echo measurements, the ToF sensor provides millimeter-accurate and robust range measurements to targets at distances up to 5m, in any lighting condition, including full sunlight, and independently of the target’s color and optical transparency.
When integrated into a Smart Door Lock system such as the K9-5F 3D Face and K11 face smart lock, the ultrasonic module will allow the system to detect if someone is approaching the door and, if a person is recognized, the facial recognition module will be awakened. The test data shows that the energy consumption of the ultrasonic module combined with the system design experience and intelligent software developed by Kaadas takes up only 10% of the energy of infrared modules, ensuring the long-term battery life of the Kaadas smart lock.
“The continued collaboration with TDK on its ultrasonic Time-of-Flight sensors has led us to adopt them in several of our leading-edge products, allowing us to make them smarter and power efficient,” said Mr. Li Xian, EVP of Kaadas.
“TDK has been recognized multiple times for cutting-edge advancement and achievements that are moving the sensors industry forward,” said Fabio Pasolini, VP and GM at InvenSense, a TDK group company. “We are strongly committed to innovation and will continue to work with Kaadas and other excellent partners in the industry to enrich people’s lives through performance sensing.”
