MinebeaMitsumi MM901 is a compact piezoresistive pressure sensor based on MEMS technology. It integrates a 16-bit ΔΣ (delta-sigma) A/D converter, enabling the output of highly accurate pressure data in digital form. The device uses an SPI interface for communication with an external microcontroller. By utilizing the built-in temperature sensor and EEPROM-stored calibration data, variations in sensor characteristics caused by temperature changes can be compensated through dedicated software running on the external microcontroller.
MMR901 features :
- Small package
- Highly accurate pressure value by installing an AD ⊿Σ converter.
Resolution: 3.3 Pa (0.025 mmHg)
Accuracy: ± 266 Pa (±2 mmHg) - Temperature compensation performed using the integrated temperature sensor and compensation data stored in the EEPROM.
MMR901 applications:
- Blood pressure monitor for home use
- Devices using air pressure
