Controlling 220v sensor


I have bought PIR sensor ( ) and i’m wondering if anyone knows how could i be able to use it with Arduino.
I want to make an alarm system with it but i don’t know how could i be able to control it with Arduino, sensor is connected to 220 V (L) and when it detect something it gives 220 V (L’). Is it even possible to use it like this sensor ?

Thank you for your answers

Drive a small AC relay with the output from the detector. Wire the relay contacts like a switch to an input. There are also ways of doing that with optoisolators although I don't know the details. At any rate you need isolation between the mains and Arduino.

Thank you very much, i will try to do that, really thanks for giving me enough information to start =)
