Introduction

The WT901C is a multi-sensor device that detects acceleration, angular velocity, angle, and magnetic field. It is designed for industrial retrofit applications such as condition monitoring and predictive maintenance. The compact size of the sensor makes it suitable for various use cases. The sensor data can be interpreted  using smart algorithms to address a wide range of applications.  The scientific name of WT901C is AHRS IMU sensor. It measures 3-axis angle, angular velocity, acceleration, and magnetic field. The sensor’s algorithm allows for accurate calculation of three-axis angle. The WT901C is employed in applications that require high measurement accuracy. It offers several advantages over competing sensors.

Warning Statement

• Putting more than 5 Volts across the sensor wiring of the main power supply can lead to permanent damage to the sensor.
• VCC cannot be connected directly with GND as it will result in the burning of the circuit board.
• For proper instrument grounding, use WITMOTION with its original factory-made cable or accessories.
• For secondary development projects or integration, use WITMOTION with its compiled sample code.
