Has anyone used this sensor with arduino and could help me implement it?
Page for the ZE25-O3 Ozone sensor: ZE25-O3 Ozone Sensor/ O3 Gas Sensor Module--Winsen.
Have you read the datasheet ?
Do you want to use the serial interface or the analog signal ?
Which Arduino board do you use ?
Have your searched and read these:

They seem to use this library:
I don't know if the analog signal can be used without a command from the serial interface.
I don't know if the serial interface can be connected to a 5V Arduino board without level shifter.
