I recommend the Guardline Wireless Driveway Alarm. You can connect it to SmartThings using a device like the Linear Contact Sensor, Ecolink Contact Sensor or Aeotec Dry Contact Sensor.
I installed mine in October of 2016 and I’ve only had a few false alarms, but I’ve never had false alarms caused by wind, rain, or snow. I live in New England so I figured it would stop working in negative temperatures, but it’s made it through 2 winters on the original batteries. There’s also a more expensive model that has a 1/4 mile range.
My only complaint about the device is that you can attach multiple motion sensors to the receiver, but it only has one “port” so there’s no way for SmartThings to know which sensor detected motion.
