Datasheet: MS5806-02BA

Description: The MS5806-02BA is a new generation of high resolution altimeter sensors from MEAS Switzerland with SPI and I²C bus interface. It is optimized for altimeters and variometers with an altitude resolution of 20cm. 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 24 Bit 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 an altimeter/thermometer function without any additional sensor. The MS5806-02BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming internal registers in the device. The gel protection and antimagnetic stainless steel cap allows the use in 100m water resistant altimeter/compass watches. This new sensor module generation is based on leading MEMS technology and latest benefits from MEAS Switzerland proven experience and know-how in high volume manufacturing of altimeter modules, which has 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.

Features:

  • High resolution module, 20cm
  • Fast conversion down to 1ms
  • Low power, 1µA (standby < 0.15µA)
  • Integrated digital pressure sensor (24 bit ΔΣ ADC)
  • Supply voltage 1.8 to 3.6V
  • Extended pressure range: 10 to 2000mBar
  • I²C or SPI (Mode 0, 3)
  • Hermetically sealable for outdoor devices
