BMA423 Accelerometer

Bosch Sensortec's BMA423 features digital, triaxial, low-g acceleration sensor with digital interfaces for low-power consumer applications

Image of Bosch Sensortec's BMA423 AccelerometerBosch Sensortec's BMA423 features 12-bit digital resolution, embedded intelligence that allows for low-noise measurement of acceleration in three perpendiculars and thus senses wrist tilt, tap/double tap, and enables plug n' play step counting especially in wearable devices. This accelerometer with its embedded intelligence is highly configurable to give design flexibility while providing low current consumption for always-on applications and wearable devices. The BMA423 is optimized for wrist bands, toys, gadgets, and wearables.
