The VELLEMAN K2644 Frost Indicator Single LED Kit is a practical electronic safety device designed to warn drivers when road temperatures approach or fall below the freezing point. By providing a clear visual indication of potentially icy conditions, this compact kit helps improve driving safety during cold weather and reduces the risk of accidents caused by frost or black ice.
The system continuously monitors ambient temperature using a high-accuracy temperature sensor supplied with a convenient mounting stud for secure installation. As temperatures approach freezing, the indicator LED begins flashing, alerting the driver that road surfaces may soon become slippery. Once the temperature drops below the freezing point, the LED changes to a continuous steady light, providing an unmistakable warning that freezing conditions are present.
Operating from a standard 10V to 15V DC power supply, the K2644 is ideal for installation in cars, trucks, caravans, off-road vehicles, agricultural machinery, and other 12V automotive systems. With a low current consumption of only 25mA, the circuit places minimal load on the vehicle's electrical system while providing continuous monitoring.
The compact 56 × 42mm PCB allows for easy installation behind dashboards or inside custom enclosures, while the remote temperature sensor can be mounted externally for accurate ambient temperature measurement.
Supplied as a self-assembly kit, the VELLEMAN K2644 is an excellent project for automotive electronics enthusiasts and anyone looking to add an extra level of safety to their vehicle during winter driving.
Whether commuting, travelling long distances, or operating vehicles in cold climates, the K2644 provides an early warning of hazardous road conditions before they become dangerous.
