MinebeaMitsumi MMR940 digitally outputs a corrected micro differential pressure value. No additional correction is required, as the module automatically compensates for sensor-to-sensor variations and temperature characteristics. It does not require a complex sensor drive or control circuit, and high-performance devices can be developed using only this module and an external microcontroller acting as the host.
MMR940 features :
- Dual-nozzle package
- High-accuracy pressure output
- Operating pressure range: −40 to +40 cmH₂O
- Effective resolution : 0.002 cmH₂O RMS
- Pressure measurement error: ±0.5% FS
- Sensor-to-sensor variations and temperature characteristics are factory-calibrated and compensated
- Digital pressure output via I²C interface
- Noise reduction enabled by a built-in low-pass filter
