A traditional weather barometer can give you a forecast of a change in the weather by gauging barometric pressure. A classic weather station will also include a hygrometer and thermometer. A hygrometer is used to gauge humidity and a thermometer to display the air temperature, all within the comfort of your home. Similar designs have been used since the 17th century. Not a circuit in sight, just an attractive wood and brass finish with easy to read dials. Check in-store for more. Weather is changeable; glorious weather one day, though rain is assured very soon. A barometer is a useful guide to the weather, and a useful feature in your house.
