The PokéStop module is for placing lures to attract more Pokémon. If you have you have a lure and click on the module slot at a PokéStop you can add it to the PokéStop and it stays active for 30 minutes. As far as finding more Pokémon, that's part of the game, you'll have to continue exploring to find them.
