The MS5840 is an ultra-compact micro altimeter. It is optimized for altimeter and barometer applications. The altitude resolution at sea level is 13 cm of air.

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 MS5840 can be interfaced to any microcontroller with I2C-bus interface.
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 has been widely used for over a decade.

Application: Industrial (air & underwater) drone, medical, wearable watches, mobile altimeter, GPS devices, e-cigarette
