The IRS21 is a passive sensor embedded in the monitored road surface, flush with the surface, to provide measurements of actual road conditions. It measures surface temperature, water-film level, freezing temperature for NaCl, and road condition (dry, damp, wet, ice or snow, residual salt, freezing). The IRS21 is a primary component of our road-weather information stations (RWIS). Two IRS21 sensors are typically installed at each measurement site.

In our RWIS stations, the IRS21 sensors are typically interfaced to a CR1000 datalogger via the 18080 interface and the SDM-SIO4.
