Those properties include temperature, relative
humidity, humidity ratio, degree of saturation, specific volume and density,
dew point temperature, wet-bulb temperature and enthalpy. The simplest way of
obtaining data regarding to psychrometrics properties of moist air is to
measure dry-bul temperature and relative humidity using simple thermometer and
psychrometer. The remainder of the properties can be determined using either
psychrometric chart or complex equations. A simple and cost-effective device is
essential to gather long-term data to be used for automation devices or other
engineering designs related to environmental control systems. An Arduino based
psychrometrics devise developed to achieve this goal. The device employs Arduino
microcontroller card. This card has a cheap and high capacity
microprocessor that can easily integrate different sensors. The device includes
temperature/relative humidity sensor and a digital barometric sensor. The
measured temperature/ relative humidity and elevation are recorded by
connecting to a remote database server over the Internet at the desired time
intervals. All other pscyhrometrics properties are calculated within the
database. The design procedure and performance of the device is discussed in
this paper along with cost information.
