Overview

The sensor module includes a pressure sensor and an ultra low power 24- bit ∆Σ ADC with internal factory calibrated coefficients. It provides a 24-bit digital pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. The MS5525DSO can be interfaced to virtually any microcontroller. The communication   protocol is simple, without  the  need  of  programming  internal  registers in the device.

This new sensor module generation is based on leading MEMS  technology and latest benefits from MEAS proven experience and know-how in high volume manufacturing of pressure  modules,  which  have  been  widely  used  for  over  a decade. The rugged engineered thermoplastic transducer is available in  single  and  dual  port  configurations,  and  can  measure absolute, gauge, compound, and differential pressure from 1 to 30psi.
