Original Press Release:



MS5806-02BA Digital Barometric Pressure Sensor Module



Measurement Specialties, Inc. (NASDAQ: MEAS) has just released to production its new MS5806-02BA digital barometric pressure sensor module. This small 6.4 x 4.0 x 2.75mm altimeter requires 6 pads for operation, uses I2C or SPI communication and has a conversion time down to 0.6ms. Operating at a low power of 0.9μA (standby <0.1μA at 25°C) and 1.8 – 3.6V supply voltage, this tiny gel-filled product with antimagnetic stainless steel cap can reach up to 20cm of altitude resolution and is more than capable for 100m water-resistant altimeter/compass watches.



At a highest resolution of 0.024mBar, this 24-bit ΔΣ ADC integrated digital pressure sensor has an operating pressure range of 300 to 1100mBar with an extension of 10 to 2000mBar, and an operating temperature range of -40°C to +85°C. Along with its ±2.5mBar typical pressure accuracy, this pressure sensor module also includes temperature measurement capabilities with a temperature accuracy of ±0.8°C and temperature resolution less than 0.01°C.



The MS5806-02BA is ideal for the high end thin watch market, as well as applications that include adventure or multi-mode watches, fitness gadgets, mobile altimeter/barometer systems, bike computers, variometers, dataloggers and waterproof cell phones.



This digital altimeter module accommodates today’s growing technologies by enabling better capabilities in new consumer electronics. Examples include fitness gadgets that could not previously afford a water-resistant sensor and GPS units that can now add “waterproof” to their designs.
