SmartSens MS2100

SmartSens MS2100 is a space-efficient integrated module that provides everything needed to design a high-resolution 2-axis digital compass or magnetic sensor module, achieving new lows for energy consumption without sacrificing size or speed.



MS2100 uses 12 times less power than ordinary sensors that devour energy by setting and resetting (degaussing) between readings. Because it doesn't need to reset, MS2100 is always ready and doesn't consume energy purposelessly. Ideal for field sensing where power supplies are few and far between, its small surface-mount package is optimized for a wide range of applications, including automotive, marine, aeronautical, and digital compass features for consumer electronics.
