All weather equipment or weather stations from the brands you refer (Lambrecht, Barani, Vaisala, Young, Delta Ohms) are in another scale of prices, generally not accessible to small or medium size companies, even less (I think ) for personal use.

In any case, under request I can develop a special TX unit which can deal with up to two PT100 sensors (2, 3 or 4 wires) and send their data to an WeatherDuino receiver, of course the price will be on another range too.

To study.... are you an expensive or cheap man?
