# Single reading from a relative humidity sensor.
# Defines the ratio of partial pressure of water vapor to the saturated vapor
# pressure at a temperature.

std_msgs/Header header # timestamp of the measurement
                             # frame_id is the location of the humidity sensor

float64 relative_humidity    # Expression of the relative humidity
                             # from 0.0 to 1.0.
                             # 0.0 is no partial pressure of water vapor
                             # 1.0 represents partial pressure of saturation

float64 variance             # 0 is interpreted as variance unknown
