Never lose your umbrella again by using the new Davek Sensor™. This little device, both small and discrete, will attach to any umbrella. Sync the sensor to your phone and it becomes a digital tether, alerting you if you ever accidentally leave the umbrella behind.

An invisible leash:  Keep your umbrella by your side
The Davek Sensor™ uses proximity awareness technology to keep your umbrella by your side. Once activated, the sensor will sync to your phone within seconds after you pick up your umbrella. If the distance between your umbrella and your phone exceeds a certain range (~30 ft), the sensor will send a subtle alert to you. Never forget your umbrella again!

Setting it up is easy. Attach the sensor to your umbrella and download our free app onto your phone (via Apple App store or Google Play). Simply hold the umbrella near the phone for 10 seconds and turn the app on. The umbrella will automatically connect. You can easily turn the alert off or pause it for the day.

The sensor is powered from a standard CR2032 cell battery, available at any hardware or drugstore, and should last for more than a full year, depending on use. The battery is easily replaceable. We've designed the sensor to detect when the umbrella is in use and when it's not. If it's not in active use, it will go into battery-saving sleep-mode. The moment you pick it up, it awakens to pair to your phone.

A Davek umbrella is a long term investment. Keep yours by your side with the Davek Sensor™.

FAQ

Where do you attach the sensor onto the umbrella?
The sensor attaches to the umbrella's canopy via a small, detachable magnet.

What is the sensor’s size?
1 inch diameter.

Is the sensor compatible with both iPhone and Android?
Yes. For iPhone, we recommend iPhone version 6 or later, using IOS 10 or higher. For Android, the sensor is optimized for Samsung Galaxy devices and performance may vary on other Android devices. We recommend Android OS 8 or higher.

How does this differ from Tile®, AirTag or other tracking devices?
Trackers like Tile and AirTag typically help you locate a misplaced item—keys, TV remote, etc.—after you've lost it. By keeping your umbrella tethered to your phone, the Davek Sensor prevents loss in the first place. Umbrellas are most often lost when accidentally left behind. The Davek Sensor is not an indoor tracker—instead, it is a digital tether. It is designed to keep an item by your side, anywhere, while in use. More here.

Does the sensor track the current location of a lost umbrella?
The app can tell you the last known location of your umbrella (or where you last left it behind). This does not necessarily mean it is the current location, however, if the umbrella has since been moved.

Is the app free?
Yes! You can download the app for free from the Apple App Store or Google Play.

Do I need to turn on the app whenever I want to keep track of the attached umbrella?
No. Once activated, the app is designed to remain paired until you switch the system off. The app will thereafter automatically connect within 30 seconds whenever you pick up the umbrella.

What type of battery is used and how long will it last?
A CR2032 coin battery, available at any hardware or drugstore. A single battery will last about 1 year or more (depending on use) and it is easily replaceable.

Can I track more than one umbrella?
The Davek Sensor can only track one umbrella at a time. You’ll need to disconnect and pair again if you wish to track a different sensor/umbrella.
