LPMS-TTLAL3

Description

The LP-Research Motion Sensor LPMS-AL3 series is a 9-axis waterproof Inertial Measurement Unit (IMU) / AHRS with multiple connectivity, such as CAN, RS232, TTL and USB. The sensors are designed with waterproof IP67 enclosure. The sensor units in this 9-axis waterproof IMU series are very versatile, performing accurate, high-speed orientation measurements. By the combination of three separate MEMS sensors (3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer) low-drift, low-latency orientation data around all three axes is achieved.

Each sensor unit contains a 32-bit digital signal processor capable of running all calculations on-board in real-time. For more information on our sensor fusion method please refer to the IMUcore description.

The sensor’s CAN bus interface allows connecting the sensor to a larger CAN infrastructure. The CAN type sensor supports a subset of the CANopen standard as well as a customizable sequential CAN message format. The amount of measurement data transmitted via CAN bus can be freely configured using the LpmsControl data acquisition software. Depending on transfer rate settings of the sensor, data rates of up to 500Hz can be achieved.

The sensor’s RS232/TTL communication uses either our proprietary LP-BUS protocol or alternatively a plain ASCII output format.
