An ultra-sensitive Swiss-precision sensor makes this Weather Station highly accurate and super-responsive. Ten functions update nearly instantaneously from sensors placed up to 330' away, so you'll never be far from an accurate, truly current forecast. A large forecast icon displays the predicted weather pattern, accompanied by a barometric pressure tendency arrow. Captures indoor minimum and maximum temperatures and humidity and outdoor temperatures with time and date. Indoor comfort level icon helps you save energy on air conditioning or heating. Accepts data from up to three wireless sensors placed within 330' range indoors or out (includes one sensor). An exceptional value.
