The Windows 10 Creators Update comes with new GPIO APIs which enable accurate and efficient measurement of pulse widths. Some devices that benefit are the DHT11/DHT22 temperature and humidity sensors, and certain sonar/distance sensors. We added the Windows.Devices.Gpio.GpioChangeReader class which lets you capture timestamps when a GPIO pin changes state, which you can then use to determine the time between change events.
