MEMS GYRO
Three-axis MEMS Gyroassembly is composed of MEMS gyro chip, temperature sensor, digital signal processing circuit, structure, and software, etc. It is used to measure the three-axis angular rates of the carrier in real-time. Can replace Sensono STIM210.
The product utilizes flexible connection technology and incorporates compensation algorithms such as full-temperature compensation, installation misalignment angle compensation, and nonlinear compensation in the software. This ensures that the product maintains excellent performance even in static, dynamic, and harsh environmental conditions. It outputs stable and reliable two/three-axis angular rate measurement data to users via a high-speed RS-422 serial port after error compensation.
