Watch OS - is it possible to gather data from all the sensors?

Question

I need to build a Watch OS application that gathers and sends the data collected from all the sensors of a series 2 watch:

• Accelerometer
• Gyroscope
• GPS / GLONASS
• Light sensor
• Heart rate

Is it possible to collect this data programmatically?

Answer 1

There is no single framework to do this, but you can access each sensor using the following framework:

• Accelerometer and Gyroscope - CMMotionManager, available watchOS2+
• GPS - CoreLocation, available watchOS2+
• Heart Rate - HealthKit, available watchOS2+, for accessing continuous measurements, use HKWorkout
• Light Sensor - this is the only one that is not available even in watchOS3
