Typical voltage supply of 5V, 12V or 24V?
Typical current consumption of 25mA (10 min - 130 max), 15mA (12 min - 100 max) or 15mA (12 min - 100 max) in condensing atmosphere respectively.
What is the lag in response or how long does it take for the sensor to return to its original "normal" state?
Low hysteresis.
What is the measurement range for the humidity sensor? Is that relative humidity or specific humidity?
Humidity measuring range of 0 to 100% relative humidity. Accuracy ±3%. In terms of Specific Humidity it measures value of 0-150g/kg.
Do you experience drift over time?
Long-term humidity stability (±0.5), Pressure (±0.5%), and Temperature (±0.3%).
