Overview
· The module integrates a high-precision gyroscope, accelerometer, and geomagnetic field sensor. It employs a high-performance microprocessor and advanced dynamic calculation and Kalman dynamic filtering algorithms to quickly solve the module's current real-time motion attitude.
· Advanced digital filtering technology can effectively reduce measurement noise and improve measurement accuracy.
· The module integrates an attitude solver, which, together with a dynamic Kalman filter algorithm, can accurately output the module's current attitude in dynamic environments. The attitude measurement accuracy is 0.2°, with extremely high stability and performance even better than some professional inclinometers.
· The Z-axis heading angle incorporates a geomagnetic sensor filter for fusion, resolving the cumulative error caused by gyroscope integration drift in the 6-axis algorithm, thus enabling long-term stable output of heading angle data. Note: Due to the magnetic field detection, calibration is required before use, and the device should be kept at least 20cm away from areas prone to magnetic interference, electronic devices, magnets, speakers, and other hard magnetic objects during use.
· The module has a built-in voltage stabilization circuit and operates at 9~36V.
· Supports serial port interface. Provides users with the optimal connection method. Serial port speed is adjustable from 4800bps to 230400bps.
· It supports cascading multiple modules, allowing users to view data from multiple devices on the PC software.
· Using the MODBUS protocol results in more stable data transmission and stronger anti-interference capabilities.
· It uses 485 level and can transmit over a distance of more than 10m.
