MS5805-02BA01 Mini Variometer Module

DESCRIPTION

The MS5805-02BA is a new generation of high resolution altimeter sensors from MEAS Switzerland with I2C 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 optomize 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 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's proven expertise and knowhow in high volume manufacturing of altimeter modules. Low hysteresis and high stability of both pressure and temperature signal.   DOWNLOAD OUR BAROMETRIC
