MEMS IMU
The six-axis MEMS inertial measurement unit is composed of MEMS gyro chips, high-performance MEMS accelerometer chips, temperature sensors, digital signal processing circuits, structure, and software, etc. It is used to measure the real-time angular rates and linear accelerations along the three axes of the carrier. It is compatible with SensonoSTIM300.
The product adopts flexible connection technology and incorporates algorithms such as full-temperature compensation, installation misalignment angle compensation, and nonlinear compensation in the software, ensuring excellent performance even in static, dynamic, and harsh environmental conditions. It outputs stable and reliable six degrees of freedom measurement data to users via an RS-422 serial port after error compensation.
