Accelerometer / Inclinometer

New High Precision and Low Noise Accelerometer and Inclinometer

Based on Epson’s proprietary QMEMS technology, the new accelerometer provides much lower noise and higher precision than other MEMS sensors. It can be used in many applications like seismic measurements and building monitoring only much bigger and more expensive servo-type accelerometers could be used in the past.
