5 FAQ

Q: Is there a mounting hole pattern?

A: Yes, there are four 3mm mounting holes at the corners of the PCB.

Q: Does this module support RS485 output?

A: This specific model outputs UART TTL levels. RS485 converters can be added externally.

Q: What is the warm-up time?

A: We recommend allowing 30 seconds for the sensor to stabilize after power-on.

Q: Can it measure vibration?

A: It is designed for static tilt angles. High frequency vibration may affect accuracy.

Q: What is the default baud rate?

A: The factory default baud rate is 9600bps, 8N1.
