MinebeaMitsumi MMR902 digitally outputs pressure values that are fully compensated within the module. Since sensor-to-sensor variations and temperature characteristics are internally corrected, no additional calibration or compensation is required. The module does not require complex sensor driving or control circuitry, enabling the development of high-performance devices using only this module and an external host microcontroller.
MMR902 features :
- Small package
- High-accuracy pressure output
- Pressure resolution : 0.001mmHg
- Effective pressure resolution : 0.020 mmHg RMS
- Pressure accuracy : ±2.0 mmHg (±266 Pa).
- Correction of differences between sensors and temperature characteristics
- Pressure data is digitally output via an integrated sequencer (SPI and I²C interfaces)
MMR902 applications:
- Blood pressure monitor for home use
- Devices using air pressure
