The purpose of this work is the development of a program for acquisition and processing the data obtained from temperature sensors in sensor networks. Wireless sensor networks application for collecting, processing, and presenting information is one of the promising areas as well as for operating procedures monitoring. Temperature, humidity and pressure are the most commonly measured phenomena in current ndustrial production. LabVIEW environment was used to achieve this purpose. Created program reads out the temperature values from sensor of the DAQ signal accessory, transmits them to the computer, process these data, and every second shows temperature values on the front panel in three measurement scales: Celsius, Kelvin and Fahrenheit. Obtained results can be used as a base for sensor network node software development.
