Ideal for anyone that lives in a large city with primarily street parking, the FenSens wireless parking sensor is a license plate frame that works with your smartphone to alert you to the distance to another car behind you.

Installed identically to a standard license plate frame, you simply pair your smartphone to the plate as well as download the accompanying mobile app on your iOS or Android phone.

When you are backing into a parking space, the app will offer feedback in the form of audio beeps and vibration feedback as well as a visual display. The closer you get to an object behind the car, the faster the beeps will play on your smartphone.

According to the creator, the battery will last approximately five months before needing to be recharged. The plate detects objects within 10 feet away and beeps to guide you within 1 foot of another vehicle or another obstacle.

The MSRP of the FenSens will eventually be $150, but early backers can pick up the plate for a $100 price point. While that may sound expensive for a smart license plate frame, purchasing that upgrade from a dealer when buying a car can cost between $500 to $2,000. Of course, you will have to pair the mobile device for each driver of the vehicle rather than having it integrated into the car’s dashboard.
