Bosch Sensortec Announces New MEMS Acceleration Sensors for Wearable Devices to Deliver High Performance and Easy Integration in Compact Packaging The BMA456 is designed for sporting and fitness tracking of wearable devices.
Integrated pedometer
New acceleration sensor from Bosch Sensortec The BMA456 includes a wearable product optimization pedometer that is directly integrated into the sensor without the need for additional external microcontrollers. It helps reduce system cost and power consumption, simplifies design, and speeds time-to-market.
Typical applications for the BMA456 include a pedometer for wearable equipment such as a fitness belt. Acceleration sensors can also be used for advanced gesture recognition, such as wrist tilt, and can detect movement, walking and static and other activities.
In the compact packaging outstanding performance
BMA456 has excellent performance and accuracy, 16-bit resolution, the noise is only 120μg / √Hz, the total life of the period of only 20 mg. The temperature offset coefficient (TCO) is ± 0.3 mg / K, ensuring accurate tracking of events under any conditions. The sensor is available in a compact package size of 2.0 x 2.0mm2 at a height of only 0.65 mm, making it easy to integrate into space-limited wearable equipment such as fitness trackers, smart watches and audible equipment.
Low power consumption - maximizes battery life
The low power consumption of the pedometer is typically less than 30μA, helping to extend the battery life of portable devices. Even during the step-by-step, the BMA456 can place the wearable device in sleep mode, helping to reduce overall power consumption.
Bosch has a complementary alternative to the range of acceleration sensors
The new BMA456 also provides complementary solutions for Bosch's existing wearable devices and smartphone sensors. For example, the BMA455 is the first acceleration sensor that integrates embedded intelligence into an independent accelerometer and further integrates Android functionality. The sensor is designed for low-power smartphone applications.
Adding intelligent functions to the accelerometer enables a variety of innovative applications while minimizing power consumption by avoiding awake application processors or additional discrete sensor hubs. The power management and user experience of the entire system can be improved by accelerometer detection and processing of motion (eg scanning, picking up and tilting). BMA455 has excellent acceleration sensor performance, the most important is the low offset, low temperature offset coefficient (TCO) and low noise level. As a result, the BMA455 ensures high performance in areas such as gaming and immersive activity tracking.
