Valencell's Benchmark™ Ear Sensor System is the next-generation biometric wearable sensor technology that helps you quickly develop your own biometric products. The modular design brings together the best available parts of a successful biometric sensor system in a smaller form factor and includes emitter/detector sensor electronics in an optimized optical package with a processor that is pre-programmed with Valencell’s PerformTek™ advanced biometric algorithms.
Features:
- Optical heart rate (HR) measurement, HR zone, HR recovery, resting HR, step rate / count, distance cycling cadence, calories, VO2, at-rest R-R interval (RRi) and heart rate variability (HRV), activity recognition (running/lifestyle)
- Single Benchmark™ module simplifies system integration
- Sensor module contains LED, detector, and accelerometer mounted to an IR-filtering window assembly optimized for sensor system accuracy
