The BMA180 3 by 3 by 0.9 mm triaxial MEMS accelerometer from Bosch Sensortec GmbH, Reutlingen, Germany, is capable of reliably detecting accelerations of 0.00025 g and tilt changes in the field of gravity of 0.25° in the 2 g measuring range. Suited for use in consumer electronics, you can switch the sensor's measurement range from ±1g to ±16 g in 7 steps, even during operations. Other features include 150 µg/rt.Hz ±0.25 mg min. noise density and max. resolution in the 2 g range; ±5 mg min. offset drift; ±0.25 mg/K offset drift; a 14-bit ADC that can be switched to 12-bit; an internal digital filter; and I2C and 4-wire SPI interfaces.
