X10 Sentinel Operational Humidity
You are here: Specs > Operational Humidity

Operational Humidity

Indicates how moist the air is

The X10Sentinel Camera is designed to work up to 85% RH (relative humidity). Relative humidity is a term used to describe the quantity of water vapor that exists in a gaseous mixture of air and water. The percentage refers to the Relative Humidity (RH) at which the X10 Sentinel PTZ Camera will continue to operate.

How do you calculate relative humidity(RH)?



RH =
(Actual Vapor Pressure)
--------------------------
(Saturation Vapor Pressure)
X 100%




Saturation vapor pressure is a unique function of temperature as given in the table below. Each temperature in the table may be interpreted as a dew point temperature, because as the ground cools, dew will begin to form at the temperature corresponding to the vapor pressure in this table.

(C)Temp(F)|Sat Vapor Prs (mb) | (C)Temp(F)|Sat Vapor Prs (mb)

Chart adapted from: Ahrens

For example, if the water vapor pressure in the air is 10.2 millibars (mb), dew will form when the ground reaches 45 degrees Fahrenheit (F). The relative humidity for air containing 10.2 mb of water vapor is simply 100% times 10.2 mb divided by the saturation vapor pressure at the actual temperature. For example, at 70 F the saturation vapor pressure is 25 mb, so the relative humidity would be

RH = 100% X (10.21 / 25.0) = 41%
