UV Light linked to sensor

Hi everyone,

I am currently undertaking a school project involving a self-sanitizing door handle. The handle uses an internal UVC light surrounded by a quartz tube.

For safety reasons:

I need the light to become isolated as soon as somebody activates a PIR sensor.
10 seconds after the PIR is activated I want the that light to be switched on for 10 seconds.
Once the 10 seconds is up I want the light to turn off. Hence the cycle starts again.

This cycle will essentially sanitizes the handle after each use.

I purchased a UV light that is meant to be used in cleaning fish tanks and has come with it's own circuit board. The input for the light is a standard 240V power point connection.

I would really appreciate some guidance here as I have limited knowledge in the electronic world.

Thanks
