The purpose of the thesis was to demonstrate the usefulness of monitoring systems and how are the weather conditions reflected in the beehive. We have set up a monitoring station and carried out different measurements. We were interested in the influences of weather conditions on the hive and in the differences of the temperatures in two consecutive days. We have used data gathered in good and bad weather. We measured the temperature in the middle and at the edge of the beehive. We discovered that the biggest deviations in temperature occured at the edge of the beehive, regardless of weather.To get a larger database we also took data from the HOBOS website for spring and summer beehive temperatures. This data enabled us to compare temperatures in the beehive in colder and wormer days. Most of the time cold weather (spring) did not influence beehive temperature, but this was not the case with the higher summer temperatures. We have also calculated the time needed for external temperature to influence the beehive temperature. In average, the biggest time delay occurred in the middle of the hive, and the smallest at its edge. Along with the temperature and time delay, we have also recorded beehive humidity data. The humidity was constant in the middle of the hive, larger deviations occured at the edge. Humidity was higher at cold temperatures. If the humidity is too high, disease and mold can appear, which can be fatal for a bee colony.
