Measurement Specialties has just released to production its new MS5637-02BA03 digital barometric pressure sensor module. This 3x3x0.9mm micro altimeter requires 4 large pads for operation and uses I2C communication. At a highest resolution of 0.016mBar, equivalent to 13cm of elevation, this 24-bit DS ADC integrated digital pressure sensor has a pressure accuracy of ±2mBar at 25°C for pressure ranging from 300 to 1200mBar and temperature from -20 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 0.6μA (standby <0.15μA) at 1.5 - 3.6V supply voltage, it boasts a fast conversion time down to 0.5ms with an oversampling selection available up to 8192. This digital barometric pressure sensor is good for high volume OEM portable or battery-operated devices such as smart-phones, tablet PCs and personal navigation devices where size is of primary concern.
