V.ALRT is a wearable Bluetooth LE device that can be used in projects that need to detect a button press. A built in accelerometer also allows for operations based on gesture control. Can create an audible tone and flash led. Waterproof to IP67 - waterproof up to 1 meter for 30 minutes.

Note that V.ALRT is not an iBeacon nor Eddystone beacon. The advertising data is only used so an app can detect the device after which Bluetooth GATT is used to communicate with the V.ALRT.

The V.ALRT can be programmed to detect a short press, a long press or a fall. Fall event detection is when there's 3 feet of freefall (~300 ms) followed by an impact of at least 3G. Raw acceleration can also be captured. The battery level can also be reported.

Can also be used with the V.ALRT iOS and Android apps that txt up to 3 contacts your location or calls up to 3 contacts when the button is pressed or the device detects a fall. The app also provides out of range and find alerts to track items.

Includes pendant (lanyard not included), belt clip and wristband accessories. V.BTTN is the same product with a different name (on the box).

Comes with access to the technical area where there's developer guide and iOS/Android sample code.
