Moisture Sensor
Sensor Activated Systems

K&K Systems’ Sign Alerts™ can be equipped with a moisture sensor that is ideal for those locations that are notorious for moist conditions that could cause traffic accidents due to the roads being slippery. With Sign Alert and the moisture sensor attachment, accidents are kept to a minimum in those areas because drivers are cautioned of road conditions. The operation is simple: when the sensor detects moisture, the moisture sensor activates the Sign Alert LEDs. The system is deactivated once the moisture leaves.

Moisture Sensor

Moisture Sensor Systems come with a moisture sensor conveniently located near the solar panel so that it can detect the first sign of moisture and quickly active the Sign Alert LEDs.
