MS580502BA01-50 TE Connectivity

MS5805-02BA01 Miniature Altimeter Module High resolution module, 20 cm Fast conversion down to 0.5 ms Low power, 0.6 A (standby < 0.15 A at 25C) Integrated digital pressure sensor (24 bit ADC) Supply voltage 1.8 to 3.6 V Operating range: 300 to 1200 mbar, -40 to +85 C Extended pressure range: 10 to 2000 mbar 2 I C interface No external components (Internal oscillator) Excellent long term stability Sealing designed for 2.5 x 1mm O-ring DESCRIPTION 2 The MS5805-02BA is a new generation of high-resolution altimeter sensors from MEAS Switzerland with I C bus interface. It is optimized for altimeters and variometers with an altitude resolution of 20 cm. The sensor module includes a high-linearity pressure sensor and an ultra low power 24 bit 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 MS5805-02BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming internal registers in the device. 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 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.
