Bosch BMA425 3-Axis Accelerometer is a compact, ultra-low power 12-bit digital triaxial acceleration sensor designed for wearable and motion-tracking applications. It integrates intelligent motion-triggered interrupts such as step counting, activity recognition, and tilt detection, reducing the need for external processing.
With support for I²C and SPI interfaces, flexible acceleration ranges (±2g to ±16g), and built-in FIFO, it ensures efficient data handling. Its low current consumption and small LGA-12 package make it ideal for battery-powered devices. The sensor supports auxiliary interfaces for magnetometer integration and offers robust performance across a wide temperature range, making it highly suitable for fitness tracking, smart wearables, and user interface applications.
Features:
- Ultra-low power consumption (as low as 3.5µA in suspend mode)
- 12-bit digital triaxial acceleration sensing
- Programmable ±2g, ±4g, ±8g, ±16g ranges
- Integrated step counter for wearable devices
- Activity recognition (running, walking, still)
- Tap, double-tap & motion interrupts
- Built-in 1KB FIFO for efficient data buffering
- I²C & SPI communication with interrupt pins
