ABSTRACT
Wireless sensor networks are nowadays used both in environmental and socioeconomic fields. Environmental monitoring includes observing of basic meteorological variables, air pollutants, volcanic activity, landslides, etc. The major purpose of wireless nodes equipped with sensors is to collect data about selected environmental variables and send them to a gateway which is a gathering point of the whole wireless sensor network Temperature and air humidity values are measured at the predefined height, orientation and recording interval. These data show weather characteristics of the area of interest in days when the measurements were realized. The changes of temperature and air humidity values can be recorded in a small area in case that the measurement units are there distributed with high density. The knowledge of temperature and humidity characteristics of places situated in the area of interest can help to discover the most suitable places for different activities that are carried out in this area. This study is aimed at the research of air temperature and relative humidity characteristics of the Botanic Garden in the centre of Olomouc City, Czech Republic. Temperature and humidity values were measured with sensors which were connected to wireless nodes, Waspmote Plug&Sense, produced by Libelium. Data from four nodes with sensors were used for the investigation of temperature characteristics. Data from one sensor recorded relative humidity characteristics. Temperature and humidity values from different positions within the Botanic Garden were graphically compared and visualized. Graph and map visualization showed the differences in measured values of selected variables in the Botanic Garden.
