Miniature altitude and barometric pressure modules
Variohm EuroSensor is promoting the miniature altitude and barometric pressure modules from its distribution partner Measurement Specialities. The MEMS-based modules feature a silicon micro-machined membrane with four implanted piezoresistors and are available as uncompensated sensor-only components or surface-mount devices with analogue outputs, or as fully-calibrated digital modules supplied in a variety of packaging and interconnection options. Applications range from mobile altimeter/barometer and weather monitoring systems to adventure watches, mobile navigation devices, variometers and dataloggers,
Recently launched digital module sensors from Measurement Specialities include the MS5607 calibrated micro-altimeter with extremely low power consumption for cost-critical, high-volume OEM products such as mobile personal navigation and smart phone embedded navigation devices. The high-resolution sensor is supplied as a QFN package and has a measurement range of 10 to 200mbar over a temperature range of -40 to +85degC with an altitude resolution of 20cm. The factory-calibrated module has both SP1 and I2C bus interfaces and can be interfaced to virtually any microcontroller. The power consumption of typically 0.15micro-amps at standby and the supply range of 1.8-3.6V DC combine with a package size of just 5mm x 5mm x 1mm to suit the latest generation of mobile devices.
Also available are the MS5803-01BA and MS5801-01BA digital modules that are intended for high-precision barometric compensation and altimeter devices. These factory-calibrated gel-filled digital output sensors feature a 24-bit resolution, which equates to 0.012bar, with excellent long-term stability over an operating range of 10-1300mbar at temperatures of -40 to +85degC. The 58xx series have an altitude resolution of 10cm and, with very low power consumption, are suitable for battery-powered depth metering and altimeter applications.
Variohm EuroSensor provides complete pre-sale and post-sale application support for the Measurement Specialities range of pressure sensors, and also designs, develops and sources a broad range of position, load, force, and other sensor technologies for demanding measurement applications throughout industry, agriculture, construction, autosports, and research.
