Davis weather stations have an optional probe.

Multi-purpose temperature probe with 2-1/2" (64 mm)-long stainless steel housing.

Use to measure temperature of air, soil, or water. Add up to four probes to a single Leaf & Soil Moisture/Temperature Station. Includes 15' (4.6 m) direct-burial cable

see davisnet.com

I have a Davis wireless weather station with readout console inside and temp/humidity/wind outside.
