Features of the relative humidity sensor*:

*According to the data sheet of the manufacturer of the relative humidity sensor

Range:
0 to 100 % HR -40° to 70°C (-40° to 158°F)
Exposure to conditions below -20°C (-4°F) or above 95% relative humidity may temporarily increase the maximum error of the additional 1% relative humidity sensor
- Accuracy:
±2.5 % from 10 % to 90 % (typical) to a maximum of ±3.5 % including hysteresis at 25 °C (77 °F)
Below 10 % HR and above 90 % HR ± 5 % typical
- Resolution: 0.01 per cent
- Drive: - Response time (typical, 90% of change)
Temperature:
Without solar radiation shield: 3 minutes, 45 seconds in the air moving at 1 m/sec
With solar radiation shield RS1/M-RSA : 7 minutes, 45 seconds in the air moving at 1 m/sec
With RS3-B solar radiation shield: 6 minutes, 30 seconds in the air moving at 1 m/sec
Relative humidity: 
Without solar radiation shield: 15 seconds in the air moving at 1 m/sec
With RS1/M-RSA solar radiation shield: 30 seconds in the air moving at 1 m/sec
With RS3-B solar radiation shield: 30 seconds in the air moving at 1 m/sec
