Miniature Altimeter with 10 mBar to 2000 mBar Pressure Range Available from Measurement Specialties Low-power MS5806 ideal for adventure and multi-mode watch applications
HAMPTON, Va., Nov. 11, 2013 /PRNewswire/ -- Measurement Specialties (NASDAQ: MEAS), an expert in sensor design and manufacturing, has released the low-power MS5806, a compact digital barometric pressure sensor module that operates over an extended pressure range of 10 mBar to 2000 mBar.
The new sensor's altitude resolution of up to 20 cm makes it ideal for use in altimeters and variometers. Measuring only 6.4 mm x 4.0 mm x 2.75 mm, the MS5806 easily fits in space-constrained devices including high-end thin watches, adventure and multi-mode watches, fitness gadgets, mobile altimeter/barometer systems and bike computers.
The new 24-bit Delta Sigma ADC integrated digital pressure sensor features several different operation modes to optimize conversion speed and current consumption. The sensor converts the device's uncompensated analog output voltage from the Piezo-resistive pressure sensor to a 24-bit value, while providing a 24-bit value for the temperature of the sensor as well.
The hermetically-sealed MS5806 features a protective cap constructed of an anticorrosive, polished stainless steel and is filled with a silicone gel protecting the sensor and bonding wires. An optional O-ring placed on the cap's outer diameter provides water-resistance to 100 m, while avoiding mechanical stresses on the sensor.
The MS5806 uses six coefficients to compensate for process variations for increased measurement accuracy as well as I²C or SPI communication to offer a conversion time down to 0.6 ms. It can be interfaced to virtually any microcontroller.
This new digital barometric pressure sensor module is based on leading MEMS technology and the latest advancements from Measurement Specialties.
- Low power of 0.9 microamps (standby <0.15 microamps at 25 degrees C)
- Supply voltage range of 1.8 V to 3.6 V
- Pressure range: 300 mBar to 1100 mBar (Extended: 10 mBar to 2000 mBar)
