MinebeaMitsumi MMS651 is a MEMS-based flow velocity sensor. It integrates a 16-bit ΔΣ (delta-sigma) A/D converter and outputs highly accurate flow velocity data in digital form. Communication with a microcontroller is performed via an I²C interface.
MMS651 features :
- Small package
- High-accuracy measurement
- AD ⊿Σ converter with 16-bit resolution
- output of high-accuracy flow velocity pressure value in the form of a digital value
MMS651 applications:
- HVAC/VAV, FAN, projector
- Devices using air flow velocity
