防止交通事故和生命损失
概览
The Wintersense SDI-12 is a remote road surface temperature sensor designed for use with your Road Weather Information Systems (RWIS). It is an easy-to-deploy, non-invasive, compact, and lightweight sensor that you can mount on existing roadside structures such as streetlight columns or RWIS towers. The Wintersense SDI-12 has a cabled connection for power and communications with an RWIS station or data logger for data storage and forwarding.
With accurate, real-time road surface temperature data, you can forecast your winter road treatments, preventing traffic accidents and potential loss of life.

技术说明
Wintersense SDI-12配备了一个热电堆传感器，可检测目标表面是否存在热辐射。该传感器还具有一个集成的光学滤波器，可切断可见光和近红外辐射通量，消除环境和阳光的干扰。这些功能与八秒信号平均算法相结合，为您提供了这些测量参数的最佳数据：
- 路面温度
- 空气温度
- 相对湿度
- 露点温度
- 安装角度
- 传感器温度
