Ultra-low-power accelerometer for IoT

Determining speed for different electro mechanics is important. An accelerometer comes handy when speed need to be established. Ultra low power accelerometer is the most ideal for IoT devices. An optimized low power device would be more privilege in IoT because it is a matter of longer battery life to achieve the best from these devices. 

Due to low-current consumption, built-in plug-in plug-and-play processes, and behavior identification functionality, the BMA400 is now made available globally through wearables, such as smartwatches and fitness trackers, Bosch Sensortec’s BMA400 is an ultra-low-power MEMS acceleration for IoT and wearables applications. It can automatically wake whenever it senses movement and switches to sleeping mode whenever the motion stops, thereby preventing the primary application processor from wake up. This function greatly reduces battery usage to prolong charging cycles. 

The BMA400’s consistent measuring capability and its always-set bandwidth, render it a perfect choice for trouble-free use with the Internet of Things (IoT) devices, including indoor weather devices and safety systems in home automation. This can prevent false alarms by, for instance, differentiating true alarms such as rotten glass from spontaneous vibrations. It is extremely low energy consumption means that battery substitution is a much less frequent task for householders. The best of this performance contributed to the successful BMA400 in the Embedded Technologies category, the coveted CES 2018 Innovation Prize. 

High-performance ultra-low power 

Until recently, accelerometer-specification engineers had to select between low power and high enactment. Now, the BMA400 has shifted, with ultra-low electricity consumption, excellent performance, and state-of-the-art functionalities, such as an integrated step counter with 4 μA alone. The BMA400 is ten times less efficient than current accelerometers. Consequently, development compromises are no longer necessary. 

Further features for the product 

  • Because of its integrated voltage regulator, the BMA400 produces consistent performance throughout a wide range of supply voltages. 
  • It provides flexible device calibration for the variables of energy consumption, noise, and output data rate. 
  • The BMA400 has an energy consumption of 14 μA at the highest efficiency, prolonged measure, and a noise density of 180 μg/√Hz. This falls to perhaps 1 μA and under in the ultra-low self-wake-up mode of the machine. 
  • The small size of only 2.0 x 2.0x 0.95 mm3 and the embedded plug-and-play step counter render the BMA400 easy to develop for new kinds of wearable devices such as frequent watches and jewelry. 

In conclusion, Ultra-low power accelerometer is an ideal choice because of its ultra-low electricity consumption, excellent performance and state-of-the-art functionalities, such as an integrated step counter
