User Interfaces

The device does not connect to a monitor, hence its user interface is limited to various LEDs that indicate certain scenarios.

• A set of light emitting diodes are used to indicate the measurement intensity of the sensors.
• A number of light emitting diodes are also used to indicate various states of the system, such as when the application has start up process has completed, when the sensor board is powered, when the LEDs boards are powered, when the usb flash memory is being written to and when it can be removed.
