Virtual Instrumentation for Handhelds

Any Tablet with an external Hardware can make a nice Instrument. The professional part lies in that external hardware and usability of the software or app. Windows Virtual Instrumentation are well known. Things like USB Scope and Data Loggers have been there for decades.

Now we have Android in which an Open Source product can be developed. The Open Source is both in Hardware and Software.

Android Virtual Instrumentation

These were some questions i got a few years back...

1 - If i had to create a crude "Lux Meter" and "db Meter" using the built-in camera and microphone on a Android Device - How would i Calibrate it ?

2 - Is there a Component(software) for Android to interlace with a Arduino Device as an external interface, This will help us make a DMM/Scope or even a Entire Lab Test bench centered around a Tablet and a Plug-in Mini Instrument Rack.

 All These Instrument Needs a USB/Bluetooth Sensors. Add Bluetooth you can carry your Tablet away from the instrument probing the DUT. (Device under Test)
