SENSORS
ROAD-SURFACE TEMPERATURE
Range: -40 ... 70°C (-40 … 160°F)
Accuracy: -40 … 60°C (±0.5°C)
Note: Accuracy is temperature dependent. The quoted accuracy is against a blackbody source within the ambient temperature range of -20 … 50°C and object temperature range of -40 … 60°C.
Resolution: ±0.01°C
AIR TEMPERATURE
Range: -40 ... 70°C (-40 … 160°F)
Accuracy: ±0.4°C
Note: Inaccuracy can be higher under moderate-to-high solar radiation.
Resolution: ±0.01°C
RELATIVE HUMIDITY
Range: 0...100 %
Resolution: 0.1 %
Accuracy: < ±3 % or better
DEW POINT TEMPERATURE (CALCULATED)
Range: -40 ... 70°C (-40 … 160°F)
Accuracy: ±1.0 °C (-35 ... 50 °C)
Note: The calculated dew point temperature is found from Tetens' equation solved for dew point with coefficients optimized for the temperature range -35 … 50°C.
Resolution: 0.1°C
