Inertial Measurement Units (IMUs) combine multiple sensors to measure and report an object's specific force, angular rate, and sometimes magnetic field strength, using a combination of accelerometers, gyroscopes, and magnetometers. IMUs are commonly used in navigation systems, robotics, aerospace applications, and virtual reality systems to determine orientation, track movement, and stabilize platforms. They provide crucial data for motion tracking, position estimation, and inertial navigation in dynamic environments.
Basic IMUs suitable for hobbyist or educational use can be relatively affordable. High-precision or industrial-grade IMUs with advanced features like low noise, high accuracy, and fast response times can be more expensive. Customized IMU solutions or IMU modules with additional functionalities may also influence pricing.
When purchasing IMUs, define the specific requirements for your application, including the desired sensor types, sensor accuracy, sampling rate, and communication protocols. Choose an IMU with the appropriate sensor fusion algorithms for reliable orientation estimation and motion tracking.
