Mitsumi Digital Output Gauge Pressure Sensors
Mitsumi Digital Output Gauge Pressure Sensors digitally output a pressure value, which is corrected in the module by a built-in sequencer (SPI/I2C). These sensors correct and output the differences between sensors and temperature characteristics. The digital output gauge pressure sensors do not require a complicated sensor drive or control circuit. High-performance devices can be built only with this module and an external microcontroller as the host. These sensors are RoHS-compliant and halogen-free. Typical applications include blood pressure monitors, CPAP gauge pressure, smart gas meters, O2 concentrator gauge pressure/breath detection, home appliance water level, and gas valve controls.
