The probe version takes the exact same LM35 silicon and encapsulates it inside a rugged, rust-resistant stainless steel tube filled with thermally conductive epoxy, attaching it to a long wire lead. This makes the probe version perfectly suited for measuring soil temperatures, aquarium water, or outdoor weather conditions without short-circuiting the electronics.\u003c\/p\u003e\n\u003cp
