The Digilent Pmod DPG1 is a differential pressure gauge module. With NXP's MP3V5010DP piezoresistive transducer and Texas Instrument's ADCS7476 12-bit Analog-to-Digital Converter, you can detect when a change in pressure between the two ports occurs and send digital information to your system board.
