Product Description
Next-Generation Inertial Measurement Unit with Error Compensation for Self-Driving Car
IMU115 MEMS IMU integrates a 3-axis gyroscope and 3-axis accelerometer to provide real-time compensated angular and linear motion data. Compact and robust, it operates reliably under -40°C to 80°C, vibration, and shock, ideal for UAV navigation, autonomous vehicles, and platform stabilization.
Product Features
- Three-axis digital gyroscope:
- ± 250º/s dynamic measuring range (500 °/s optional)
- Zero bias stability: 10 °/h (GJB, 10s, typical value), 6.0 °/h(ALLAN, typical value)
- Triaxial digital accelerometer:
- ± 4g dynamic measurement range (configurable 16g)
- Zero-bias stability: 0.12 mg (GJB, 10s), 0.065 mg (ALLAN)
- High reliability: MTBF > 20000h
- Guaranteed accuracy within the full temperature range (-40℃ ~ 80℃): built-in high-performance temperature calibration and compensation algorithm
- Suitable for working under strong vibration conditions
- Interface 1-way UART
Field of Application
- Intelligent driving
- Communication in motion
- Mapping
- Stabilize the platform
