Azarhi Sensors provides the data from all the iPhone or iPod touch sensors. This includes location, acceleration and compass information.

Not all data is available on all touch devices. Continuously running this application will significantly reduce battery time.

Azarhi Sensors provides:

• Location data

• Bearing/Heading data

• Acceleration data

• A map showing your location based on the most recent available data

The Location tab provides latitude, longitude and altitude using GPS data, if available. Otherwise, location is based on WiFi hotspot data and/or cell phone tower locations. Apple's sensors provide accuracy information. The date and time of the most recent location update is provided; this is most important when location is provided by non-GPS sources. An option allows location to be displayed in degrees or degrees/minutes/seconds.

Note that latitude & longitude data is provided in positive and negative degrees. Negative longitude is west longitude, negative latitude is south latitude; this is unprocessed data provided by Apple's touch devices. For the same reason, distances are reported in meters.

The world map button shows the map of your most recently measured location. The Desired Accuracy selections will not have much effect for non-GPS locations. Selecting greater accuracy (10 m or <10 m) will cause the battery to be used at an even greater rate.

The Bearing tab provides heading data, including magnetic north and true north, along with accuracy. This data is valid on iPhone models that have the compass sensor. Speed and course data are available for models with GPS transceivers.

The Acceleration tab reports the data from accelerometers found in all touch devices. The data is reported in units of Earth Gs for each of the three axes. At rest, the total acceleration should be about 1 G, although these data will vary from device to device. Accelerometers do not provide great accuracy; even at rest, you will probably experience variations in the second decimal place.

There is also considerable "bleed" across the acceleration axes; for example, acceleration in the X-axis will bleed into the Y and Z axes. So, don't expect to do the next great scientific experiment with these sensors!
