Big Wind Day: A Gusty Commemoration

Big Wind Day, observed annually on April 12, commemorates a remarkable meteorological event that unfolded exactly 90 years ago. On that blustery day in 1934, atop the Mount Washington Observatory in New Hampshire’s White Mountains, the wind reached an astonishing speed of 231 miles per hour. This f... (read more)

Originating in 18th century in Japan, early pedometers were basic pendulum mechanisms. Thanks to advancements in MEMS DC capacitive accelerometer technology, pedometers have transformed into advanced tools, offering detailed insights into our physical activity.

Once only used in aerospace and military applications, MEMS accelerometers were rapidly embraced by the electronics indus... (read more)

Why does the accelerometer read zero G's when it's in free fall?

All accelerometers are used to measure increasing or decreasing acceleration, and they can detect vibration because it is a change in acceleration between multiple directions. Free fall, by definition, is a static acceleration, which means the object may be moving, but its acceleration is not changing at all.... (read more)
