THE PROBLEM

It has happened to many of us. We’ve left home or office and shortly after leaving, we started wondering whether or not we locked the door properly… How many of us have not experienced the stress and preoccupation throughout the whole day, party or trip for this reason?

Locking a door is such a repetitive task that we can hardly remember it ; That’s where the confusion starts.

Some Facts:

  • Around 60 percent of burglars used forcible entry to gain access to a home. A surprising 30 percent entered home through an unlocked door, window or other opening without resorting to force.
  • About 33 percent of intruders enter a home through the front door.
  • According to the FBI, the average dollar loss per burglary in the U.S. is $2,185

A Maker’s solution to this annoying problem from KPHOB. It is a key fob that registers the time and the date of each time you lock or unlock a door, so in case that you have any doubts, you could check the records and make sure you did lock the door last time you left the house.

KPHOB combines two sensing methods to detect key usage and key rotations.

You would be required to place a tiny permanent magnet on the doors that matter to you. This magnet serves to activate the proximity sensor that is deployed in the key fob. As a result, every time your key fob is in a certain proximity to the door (5 cm or less), it would wake up the device from standby mode, register the time and start monitoring further motions of the key. Although for many of us, just knowing the time of last key usage might suffice to deduce we have locked the door, there are drawbacks with this method. The problem is that you might also activate the key fob if you are in vicinity of any magnet, even those which are not related to the door lock…

To avoid that false detection, we also use a magnetometer so we can measure the relative orientation of the key fob and consequently the key itself towards the magnet.

On the KPHOB Kickstarter page you can back them, 20 days to go!
