Patent abstract
Improved roadway freezing point monitoring systems and methods include improved sample wells for the accurate measurement of the freezing point of liquid on a roadway, the use of temperature sensors that require only two conductors to receive power and to send and receive digital address and temperature information, improved algorithms for detecting the freeze point of liquid on the roadway, the use of conductivity measurements to verify detected freeze points, and the transmission of temperature information via the Internet to remote computers.
