Do the local animals think that your front lawn is their personal toilet? Do ninja assassins keep trying to sneak into your house? Keep these unwanted visitors away with a motion activated sprinkler system. As soon as they step into your lawn, a passive infrared motion sensor detects the intruder and turns on the sprinkler to chase them away.
