Let your objects speak to you. A cool new product from Supermechanical connects to your stuff -- refrigerators, car doors, whatever -- so they can communicate with you.
Twine is a wireless module that connects to the internet. It comes built in with two sensors (temperature and speed) but you have the opportunity to add more. You set rules to trigger messages. For example, add a moisture sensor, hook it to your bathtub and then write a rule on the accompanying app that tells it to text you when the moisture level gets too high. Voila -- your bathtub won't flood. You can also set it to tweet or email.
This is a Kickstarterproject.
