Overview
The WKF300 is a BLE key fob built for driver identification and panic alert use. It is designed to give a simple way to link a driver to a vehicle and send an emergency signal when needed.
This device works on 2.4 GHz and supports BLE 4.2 for short-range wireless communication. It can broadcast data continuously from every 1000 ms to 5000 ms for driver status monitoring, or send a one-time broadcast for an emergency alert.
The WKF300 helps monitor driver presence by sending regular status data. It also includes a low power alarm, with the battery condition indicated in the data sent to the receiver, so the system can flag when replacement is needed.
The device uses a CR2032 button battery, which keeps installation simple and supports long operating life. The datasheet states up to 3 years of battery life under light daily use with continuous broadcast turned off, or about 1 year when broadcasting every second.
The compact 56 × 41 × 8 mm body and 22.3 g weight make it easy to carry as a key fob. Its operating range of -20 °C to +60 °C also makes it suitable for everyday vehicle and field use.

Applications
The WKF300 fits fleet operations that need a simple way to identify drivers and connect them to vehicle activity. Its regular BLE broadcasts support driver status monitoring, while the panic button adds a fast alert option for urgent situations.
In taxis, delivery vehicles, and service fleets, the device can help confirm which driver is using a vehicle at a given time. Its compact key fob design and long battery life make it practical for daily carry and low-maintenance use.
The one-time emergency broadcast function makes the WKF300 relevant for workflows where a fast distress signal is important. This can support driver protection programmes and incident response processes without adding complex hardware inside the vehicle.
The device also suits operations that need lightweight BLE-based identity and status tools across shared or managed vehicles. Its low power reporting helps maintenance teams know when battery replacement is needed before service is interrupted.
