It’s a common problem. After leaving the house, it’s often hard to remember if the door was locked and it’s just too time-consuming a lot of the time to return home and check.
Kphob is a key fob that records whenever the user locks a door with an attached key. It uses several sensors, including a magnetometer and accelerometer, to track every motion of the key. The device also tracks the time and date of each entry and exit. It features a small display that shows the date and time.
Kphob ships in December. Future pricing is expected to be about $18. Early bird Kickstarter backers can get one first with a pledge starting at about $21. Its makers hope to raise $18,242 by May 5.
Alas, the fob only works only with physical keys, so consumers who have only a remote-controlled lock need not apply. Users must physically rotate the key inside the keyhole for at least one full rotation/revolution. But its makers are working on the algorithm to make it possible for 180-degree rotation detection.
