Installation Precautions

• Install using the correct method; incorrect installation can cause measurement errors.
• The sensor must be tightly mounted with a smooth and stable contact surface.
• If the mounting surface is uneven, angle measurement error may occur.
• The sensor axis and the axis to be measured must be parallel; it is best not to introduce an angle between the two.

Supporting Information

• Sample programs: STM32 sample program, Arduino serial library, 51 serial port routines
• The product does not provide schematic source code.
