1. Product Overview
The Induskey INK412 is an integrated, all-in-one traffic meteorological monitoring instrument designed for highway and roadway deployment. Utilizing embedded systems, optical sensing, and digital electronics, the unit combines multiple sensors into a single compact enclosure to simultaneously monitor air temperature, relative humidity, wind speed and direction, precipitation, road surface conditions (dry, damp, wet, snow, ice, ice-water mixture), road surface temperature, and atmospheric pressure.
A built-in microcontroller integrates all sensors and communication interfaces at the circuit-board level. The device is specifically engineered for road traffic applications, offering plug-and-play installation on existing infrastructure such as lamp posts, monitoring poles, and gantries. Monitoring data is transmitted in real-time to the control center to support traffic management decisions and enable timely warnings under adverse weather conditions.
