It’s a DIY Android Breathalyser. It’s still in prototype form, but is shown working in cable-less form, courtesy of Bluetooth.
Note you would need a phone with Android 2.3.3+ (“Gingerbread”) – for the requisite Bluetooth support – or else old-fashioned USB cable connectivity will be required…
The IOIO board works with a Seed Studio alcohol sensor – which are “the brains”, says the commentator. This was uploaded by “OpenGadgets”, and it is not clear if this is the work of Michael Mitchell – a PhD Computer Science student at FSU – but Mr Mitchell does showcase similar IOIO-based examples on his website MitchTech.
For his breathalyser, he lists the parts needed as:
* Android Device (1.6+, 2.1 for Bluetooth)
* IOIO (available at Sparkfun)
* 330 ohm resistor
* Alcohol Gas Sensor MQ-3 (available at Sparkfun)
* Power supply
* Hook-up wire
And he provides a link to his source code, and IOIO Bluetooth library projects…
