Design of Icy Detection System for Highway Pavement Based on CC2430

The design of icy detection system for highway pavement is proposed, which fuses information of vibration spread, temperature and conductivity changes to judge road icy conditions. The general schematic of hardware design is given in this paper. The CC2430 microcontroller is used in the design, so the hardware structure is simplified, and the cost-effective of the system is raised. As a node in wireless sensor network of the automatic meteorological station, the system has feature of flexible networking, low power consumption, high precision and high reliability.
