Its 3-axis Accelerometer captures and records continuous, high resolution physical activity and sleep/wake information while its Ambient Light Sensor provides minute-by-minute light intensity values alongside activity information which is helpful for examining the relationship between environment /activity and sleep behaviors.
The Wear Time Sensor automatically detects if a wrist worn device has been removed for simplified compliance monitoring and data cleaning.
