Can I interface zphs01b with arduino

This clip from Arduino.
RS232 devices use high voltages that are not compatible with an Arduino's TTL voltage levels and may damage an Arduino. You can use a device such as a MAX232 to convert between RS232 and TTL voltage levels.

If the TS connect the sensor to the Arduino Serial Port pins, he must have a level shifter,

There is so much contradictory information on the web, I am going to check the Board levels with a scope.

Added: from the official Arduino site
Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don't connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board.
