How Does a MEMS Accelerometer Work?
MEMS is a chip-based technology, known as a Micro Electro-Mechanical System. Sensors are composed of a suspended mass between a pair of capacitive plates. When motion is applied to the sensor, the suspended mass creates a difference in electric potential. The difference is measured as a change in capacitance.
A MEMS sensor provides the convenient features available with any other sensor line, but you don’t need to concern yourself with space constraints. MEMS utilizes very compact micro machine components so small that each sensor can fit into the palm of your hand. They have an IP67 seal and since the operating temperature range is -40° to +85°C, they will withstand some intense conditions.
These sensors are great solutions to applications that do not demand the highest accuracy such as industrial automation, platform leveling, position control, and pitch and roll measurement.
