Accelerometers, Gyros, GPS, & Compasses. Measure acceleration and track rotation with these accelerometers, gyroscopes, compasses/magnetometers, and combined inertial measurement units (IMUs) and orientation sensors.
The DE-ACCM6G from Dimension Engineering is an off the shelf 2 axis ±6g accelerometer solution with analog outputs. It features integrated op amp buffers for direct connection to a microcontroller's analog inputs, or for driving heavier loads.
This is a 4WD IG42 single bearing platform that includes autonomous GPS navigation. A full array of sensors including a Pololu IMU, motor encoders, and a Garmin 18x 5 Hz GPS that work together to provide waypoint navigation with up to 3 meter accuracy.
