Frequently Asked Questions

What is the communication protocol for this ultrasonic sensor?

The sensor uses an RS485 serial interface with a Modbus communication protocol. This allows for reliable data transmission over longer distances and easy integration into industrial networks or multi-sensor setups with configurable device addresses.

Can I power this module directly from a 5V Arduino or 12V battery?

Yes, the module's wide 3.3V to 24V DC operating voltage range makes it directly compatible with 5V microcontroller boards like Arduino, as well as 12V or 24V industrial power supplies and battery systems, without requiring a voltage regulator.

How does the sensor handle interference from other ultrasonic devices?

It incorporates intelligent acoustic processing technology that identifies and filters out same-frequency ultrasonic waves. This significantly reduces the probability of interference, ensuring stable and reliable distance measurements even in environments with multiple ultrasonic sensors operating nearby.

Is the sensor suitable for outdoor use?

Yes, the sensor features a housing with a high IP rating for dustproof and waterproof operation. This, combined with its wide operating temperature range, makes it suitable for outdoor applications such as automated guided vehicles (AGVs) or outdoor parking systems.
