MS5803-01BA07-Digital Pressure & Altimeter
Brand: American Sensor Technologies IncMS5803-01BA07-Digital Pressure & Altimeter
Brand: American Sensor Technologies IncThe MS5803-01BA07 is a new generation of pressure sensors with improved resistance for harsh environment and outstanding resolution of 12 µbar.
The sensor module includes a high linearity pressure sensor and an ultra low power 24 bit ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption.
A high resolution temperature output allows the implementation of a pressure/temperature function without any additional sensor. The MS5803-01BA07 can be interfaced to virtually any microcontroller. The communication protocol is standard I²C and SPI interface. Special gel protection and antimagnetic stainless steel cap allows the use in harsh environment.
This new sensor module generation is based on leading MEMS technology and latest benefits from MEAS proven experience and know-how in high volume manufacturing of pressure sensors, which have been widely used for over a decade. The sensing principle employed leads to very low hysteresis and high stability of both pressure and temperature signal.
