The industry's first three axis MEMS accelerometer to include custom motion recognition has been touted by STMicroelectronics.
Designed to reduce power consumption and increase design flexibility in consumer electronics, the LIS3DSH features two embedded finite state machines, which allow the user to implement customised motion detection based applications, reducing the workload of the microprocessor by moving programming functionality inside the sensor.
According to ST, these basic programs identify specific motions or gestures, custom defined in the instruction set that runs inside the sensor firmware, and initiate associated actions or applications. In addition, the sensor is said to provide extremely accurate output and excellent stability over time and temperature.
"Integrated processing capability in MEMS sensors decreases power consumption at the system level, which is especially crucial in battery hungry portable devices," said Benedetto Vigna, corporate vp and general manager of ST's Analog, MEMS and Sensor group. "An industry unique feature, programmable state machines embedded in the sensor, also bring more freedom and flexibility to the design of motion enabled consumer electronics."
