The driver adds support for the Veris TEAMS Temperature Transmitter. It provides it's output via a 4-20ma current loop. The supported temperature range is 10C to 35C. This sensor was developed with a Cooking Hacks (Libelium) 4-channel 4-20ma Arduino interface shield. For this interface, the receiver resistance (rResistor) was specified as 165.0 ohms.
