Measurement Specialties’ new MS5637-02BA03 is a digital barometric pressure sensor module measuring just 3 x 3x 0,9 mm and requiring only four large pads for operation.

It uses I²C communication and at the highest resolution of 0,016 mBar (equivalent to 13 cm of elevation) its 24-bit delta-sigma ADC produces a pressure accuracy of ±2 mBar at 25°C for pressure ranging from 300 to 1200 mBar and temperature from -20°C to +85°C.

The pressure sensor module also includes temperature measurement capabilities with a temperature accuracy of ±2,0°C and temperature resolution less than 0,01°C. Operating at a low current consumption of 0,6 A (standby <0,15 A) at 1,5 - 3,6 V supply voltage, it boasts a fast conversion time down to 0,5 ms with an oversampling selection available up to 8192.

The MS5637-02BA03 is ideal for high-volume OEM portable or battery-operated devices such as smartphones, tablet PCs and personal navigation devices where size is of primary concern.
