Wireless IMU (inertial measurement unit) SAG200 is an 9-axis attitude and heading reference system (AHRS). The sensor consists of wireless accelerometer, wireless gyroscope and wireless magnetometer. Wireless IMU SAG200 has the best battery efficiency in the industry. When taking 9-axis measurements, computing pitch, yaw and roll angles, and transmitting the results to Broadsens edge-computing gateway at the same time, the total power consumption of SAG200 is less than 5mA.
Wireless IMU SAG200 computes the Euler angle inside the sensor, and output 16-bit 3-axis acceleration, 3-axis angular rate, 3-axis compass, and pitch, yaw and roll angle in real time. SAG200 can be used for both dynamic and static angle measurements. Both the acceleration range and angular rate range are user-adjustable. Multiple wireless IMU SAG200 can be allocated to the same group for parallel monitoring. For a heavy machine, multiple points can be monitored at the same time with SAG200. Moreover, SAG200 can be assigned to different groups, and each group can take measurements with timer for automatic monitoring.
Multiple wireless IMU SAG200 can be controlled remotely from clouds using the advanced remote function of the edge-computing gateway.
