Outdoor Measurement

Outdoor measurement of temperature, relative humidity, and barometric pressure, is needed to calculate the enthalpy of outdoor air. With similar information from the spaces within the building, the building automation system is able to calculate the most efficient way to reach desired conditions within the building. Wind speed and direction measurements can also be used to improve the control of ventilation.
