Wi-Fi Enabled TDK Invensense ToF Sensor to Cloud

Presence detection plays a crucial role by transitioning efficiently between active and sleep states, activating only when human presence is detected, thus significantly extending battery life while maintaining responsiveness. In battery-operated security cameras and smart home devices, reliable presence detection is particularly vital as it enables event-triggered recording and notifications, eliminating unnecessary power consumption from continuous operation or false triggers.

The challenge lies in implementing presence detection technology that balances power efficiency with detection accuracy – ability to work in diverse surroundings and minimizing false positives. Success in this balance directly impacts device reliability, user satisfaction, and maintenance costs, making it a critical consideration in battery-powered device design. TDK InvenSense’s Ultrasonic Time-of-Flight (ToF) sensors offers better power and detection efficiency compared to passive infrared (PIR) and mmWave radar sensors.

InnoPhase IoT has added support for TDK InvenSense’s ICU-30201 Ultrasonic ToF sensor. The combined solution offers a turn-key always-on, always-connected solution that can be used in battery-powered applications that require a secure and reliable connectivity to interact with local devices and remote accessibility. The solution can be used as a standalone or with an external host depending on the application requirements.
