A couple of things stand out. How is your detector wired up? You have it defined as an input but it may need to be an INPUT_PULLUP so that it is not floating.
I hope you are not trying to drive a solenoid directly with an arduino pin. They can ony deliver 40mA and a solenoid will take way more than that.
A schematic, even hand drawn, would be useful.
