Why? Well if you've got your washing on the line and get your head into completing a report, watching Hollyoaks or distracted by the kids, you may not notice that the good old British weather has turned damp.
The Clever Peg is able to sense precipitation in the air and give your iPhone a buzz to alert you that rain is on the way. You can then dash outside and bring in the washing before it gets wet all over again.
The solar-powered device requires no independent power source as it has a solar panel strip along the length of one side. The Clever Peg iPhone app can be downloaded for free from the iPhone App Store.
The Clever Peg costs £39.99 from Firebox.com.
