Can I make this a 0v output when triggered instead of a 5v ? There are three solder pads on the board with L and H next to them , do I link them?

The module is active high only I'm afraid. Your easiest option would be to either add a relay or a transistor to the output pin to flip the polarity.

I believe these are for setting the trigger mode (see datasheet).
