Benchmark Biometric Sensor System for Wearable Devices
BW1.5
Valencell Benchmark Sensor Systems are complete biometric sensor systems that include all the hardware, optomechanical design, firmware and algorithms for highly accurate biometrics in wearables of all shapes and sizes.
Description
The PerformTek-powered BW1.5 sensor system is an evolution of the BW1.4 sensor technology developed by Valencell, Inc. BW1.5 has been updated to simplify system design by supporting LED operation with a power input directly from a lithium polymer battery. This sensor is intended to be a drop-in replacement for BW1.4 I2C-based sensors. The modular design brings together the best available parts of a successful biometric sensor system in a single, optically optimized package pre-programmed with Valencell’s PerformTek advanced biometric algorithms. Features
- Market-leading quality optical heart rate (HR) measurement, step rate / count, distance, cycling cadence, calories, R-R interval (RRi) and activity recognition (running/lifestyle)
- Single Benchmark® module simplifies system integration
- Sensor module contains a processor, LEDs, a detector, and an accelerometer mounted to a window assembly optimized for sensor system accuracy
- PerformTek® low-power ARM® Cortex® processor performs sensor data processing and provides a communication interface to the system host processor.
