Temperature

Temperature
Range	-40–60 °C (-40–140 °F)
Resolution	0.1 °C (0.1 °F)
Accuracy	±0.3 °C (±0.5 °F)
Long-term drift	0.03 °C/yr (0.05 °F/yr)

Relative Humidity

Relative Humidity
Range	0–100 %RH
Resolution	1 %RH
Accuracy	±2 %RH
Long-term drift	0.5 %RH/yr

• RH accuracy valid for 0–80 %RH at 23 °C (73 °F). Drift quoted for lab conditions (23 °C, 30–70 %RH); may be higher otherwise.
• Prolonged exposure >80 %RH (condensing) can temporarily increase readings; dry the sensor in low RH to normalize.
