Here is a doormat that sends you a text when it detects the weight of people or pets: SmartMat uses a smart force-sensitive plastic film that connects to your WiFi network to carry out tasks and monitor your home in real time. Different combinations of triggers and actions are available. You can use SmartMat to send text alerts, control WiFi connected power strips, update Twitter, or control home security products.
SmartMat can let you know when your pet is at the door, wanting to come in. You can set it up to get alerts when someone leaves your home. Want to get notified when your package arrives? No problem. You can even use a system like this to turn room lights on when someone enters. The possibilities are limitless.
SmartMat has a battery life of 3 days (continuous use) but you can use the included AC adapter to run it as long as you want. A power saving mode is available, so you can get much longer out of your smart door mat. Like what you see? You may want to support it on Kickstarter.
