Abstract
Road surface sensors system, which monitors the road conditions and raises an alarm when necessary, plays a very important role in the safety of transportation. The temperature detection sensor is used to measure the temperature on and beneath the road surface. It synthetically estimates the road conditions in cooperation with other sensors, such as water film sensor, salinity sensor and so on. In this paper, the theory, circuit structure and testing method of the temperature detection sensor have been introduced, and the data processing pattern and accuracy of results have been improved.
