Dati dei sensori incorporati sono viste e catturate su un registratore a nastro virtuale-chart.

Note: Performance of this application is device dependent, ie; newer speedier devices do better.

1. Description

SensorUtils is a utility program built around the notion of a strip-chart recorder. Inputs to the recorder are sensors built into the Android device. The recorder displays graphically the sensor readings on a strip-chart like graph. There are three channels on the recorder that can used for each sensor. The strip-chart graph can be saved as a screen shot (device app) or data collected can be saved to a file.

NOTE: The screen must be active for the application to collect data. Once the screen is turned off or another app is run, the data collection will stop.

2. Operation

Launch the application. SensorUtils will query your device for available sensors. One sensor will be shown on the selection button. Each time the button is clicked another sensor is shown. The button will eventually return to the first sensor displayed. Typical of physical measurements available include acceleration, magnetic field, orientation, proximity, light intensity, and barometric pressure.

Note that the data is returned by the device to the SensorUtils application asynchronously. The device will return the data at the rate that it sees fit in order to let other applications perform properly. SensorUtils may be interrupted by an incoming call or an user action -- if the SensorUtils application is off the screen any recording in progress in be saved and the application will release any requests for sensor data. Users also need to consider that other applications make use of the sensors. The effect of this is that the rate that SensorUtils receives updates decreases, perhaps significantly.

Please read the Android developer document “Sensors Overview” for more information.
