[HWT101CT] Z-Axis 1000HZ IP68 Z-Axis 0.1°Crystal Inclinometer, MEMS Tilt Angle Sensor

If the module is not connected through a microcontroller, connect it directly to the module using a USB-TTL adapter. Then, in the PC software, select the model HWT101CT. After the data appears, click the "Configuration" button in the top right corner. In the configuration interface, check that the bottom right corner shows "Online" status. Then click "Auto Zero Bias Calibration" and wait for it to complete. Note: Modifications or settings will only take effect when the configuration interface is online. If it is offline, changes will not apply. In this case, check for cold solder joints, poor soldering, or issues with the adapter.
If the module is connected through a microcontroller, you need to implement the auto zero bias calibration commands in your own program. The specific commands are as follows, or you can refer to our STM32 or Arduino API libraries, which allow you to send the corresponding characters directly via the UART Interface to complete the calibration. 1) Auto Zero Bias Calibration: FF AA 48 01 00; 2) Delay 20s; 3) Normal Mode command: FF AA 48 00 00.

In environments with significant vibration, angle accuracy cannot be guaranteed. You can try adjusting the threshold values, but it depends on the actual measurement in the specific environment. Generally, micro-vibrations are acceptable for applications such as model cars and robots.

When the module is connected to a microcontroller, view the data directly in the serial port assistant, not in the PC software. The data passing through the microcontroller has already been parsed and is output in ASCII format. If you need to view data in the PC software, connect the sensor directly to the USB-TTL adapter without going through the microcontroller.

It is calculated through angular velocity integration and does not include a Magnetometer. It can measure the Heading Angle, but it is only suitable for horizontal motion, not spatial motion. Spatial motion will cause angle drift. The data will be saved after power-off (Non-Volatile).
