Hacker and enthusiast Gus from our nation's capital had a problem with mould in his flat, so attempted to purchase a humidifier to help even out the atmosphere at home. Not having a model with a humidistat immediately available from the retailer, he purchased a manual unit and created his own controller. Using some remote weather sensors from eBay, Gus hacked into the wireless signal from those which are received by an Arduino board with wireless data receiver. With some other hardware the temperature is also measure and the data graphed for viewing on the web. Finally the humidifier is remotely controlled by a wireless mains outlet, saving the need for AC wiring. Well done Gus.
