Twine helps you detect small problems before they become big problems. Get notified of changes in moisture, temperature, vibration and more, even when you're not home. Prevent costly damage to your home - get an alert when your basement floods, the pipes freeze, or your water heater leaks. The external sensor port lets you use a different sensor later, such as a magnetic switch, breakout board, or Cloud Shield.
Twine is the simplest way to get the objects in your life emailing, texting*, calling* or tweeting. The Twine + Moisture Sensor kit includes Twine (with internal temperature and orientation sensors), an external moisture sensor, and a 3' cable. Twine runs on external power or two AAA batteries and connects to the Internet via your Wi-Fi network. A simple web app lets you monitor your Twine and tell it when to alert you with human-friendly rules - no programming needed.
