TE Connectivity – MS5837-02BA Ultra Small Gel Filled Pressure Sensor


logo_TEConnectivity_new      NPI_LOGO
TE Connectivity’s (TE) MS5837-02BA is an ultra small gel filled pressure sensor optimized for both altimeter and barometric applications.

This waterproof 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 with 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 MS5837-02BA sensor can be interfaced to any microcontroller with I2C bus interface. The communication protocol is simple, without the need for programming internal registers in the device.
