MinebeaMitsumi MMS601 is a compact differential pressure sensor based on MEMS technology. The thermal MEMS structure enables high-accuracy measurement even at low pressure levels. The sensor integrates a 24-bit ΔΣ (delta-sigma) A/D converter and outputs highly accurate pressure data in digital form. An I²C interface is used for communication with a microcontroller.
MMS601 features :
- Small package
- High-precision measurement with low pressure level
- AD ⊿Σ converter with 24-bit resolution
- output of high-precision pressure value in the form of a digital value
MMS601 applications:
- CPAP,Ventilator,HVAC/VAV
- Devices using air differential pressure
