If you are always worried about the windows of your home being left open or cracked by some bad guys while being away, here is some good news for you. A new sensor system developed by researchers at the Fraunhofer Institute for Integrated Circuits IIS, in collaboration with Calw-based Seuffer, can detect if windows in your home are opened, wide opened, cracked or closed. The sensor system then transfers the data to the base station at the main door, which could be a tablet, smartphone or a room controller. Moreover, the sensor system that’s fixed on to window frame sends the data remotely, which lets homeowners keep a tab on their windows via smartphones.
