ACCELEROMETER - What it is and how it works
Ғылым және технология
What is an accelerometer? Which of the three types, MEMS, piezoresistive or piezoelectric accelerometer is better for your application/project? All about those g-sensors in this video and in TME: www.tme.eu/pl/en/katalog/?sea... An accelerometer is a type of sensor that measures the acceleration and vibration of a body. It is implemented in many devices such as car dash cams, laptops and, cellphones. Even sports clubs use a g-sensor to collect more data and improve their game.

Extremely helpful, thx
At 1:42 in the video, the axis definition is misleading. Assuming if I push the device in the X or Z direction I would read a positive acceleration, the Y direction is being pushed up by ground reaction, and thus should read negative on 'y'. It is a common misunderstanding to confuse gravity with what an accelerometer senses. yes, gravity pulls objects down, and if not resisted by anything an object will be in free fall, effectively accelerating but an accelerometer will read 0. As soon as freefall is resisted, the accelerometer will observed an upwards acceleration (not down!). An accelerometer does not sense gravity, it senses acceleration. Gravity just puts an offset on the observed acceleration.
excellent work. Thank you.
Best explanation, great visualization and a neat scientific tip at the end for good measure haha Thanks a lot!
Tyvm bro 🥰🥰
Interesting
Awesome
