Crossplatform app to collect accelrometer and GPS data

Delicerables: Using Xamarin as tool for the ability to compile to IOS and Android, I want you to provide source-code + compiled binaries that can : Functionality 1. Test for the existance of sensors on the phone (Accelrometer, air pressure, light, etc.) 2. Enumerate the available sensors. 3. Record sensor data to phone memory. In case of real-time, the raw data must be streamed to a file. In case of 5-second interval, the data will be buffered, and the average values of the data across the timespan will be logged. 4. Send the data by mail, by attaching file to mail. There will be one screen only, consisting of 1. Outputs, showing the current value of the sensors, as well as the name of the sensors, 2. A listbox where it is possible to select rea-time or 5 sec. logging. 3. A button that will open the default mail app for the device, and attache the logged file.
