Abstract

In energy saving and management, environmental parameter monitoring is very important role. For supporting them, five monitoring sets were conducted in two buildings. Every set consisted of illuminance, temperature and humidity sensors, which were equipped with a 4-20 mA transmitter each. The transmitter signals entered to the PLC analogue modules and the SCADA installed computer wirelessly. The parameter quantities could be recorded automatically by the computer. The obstructions of building walls could be minimized by using router and repeater installations on some parts of network. Most of the data could be recorded properly. The average temperatures and relative humidity started to rise and decrease in the range of 6:30 until 8:40 a.m. Meanwhile, the average illuminance rose between 5:40 and 6:20 a.m. and disappeared between 5:50 and 7:20 p.m. The rooms were mostly in the warm thermal comfort. In small part of time, the rooms were in the optimal thermal comfort. The warm and optimal comforts occupied 44.4 % and 19.1 % respectively. The rest, 36.5%, exceeded the comforts. Naturally, there was not any room in cool thermal comfort. The illuminance and temperature modelling convexes upward significantly indicated by the negative constants of the quadratic time variable. To meet the standard requirement of 250 lux, the illuminance covered 65.0 %, 6.7 %, 76.7 %, 45.0 %, and 36.7 % of working time for PLC 1 up to PLC 5 respectively. In contrast, the relative humidity modelling convexes downward considerably indicated by the positive constants of the quadratic time variable. This case was also reinforced by the absolute numbers of correlation coefficients among the illuminance, temperature and humidity that were above 0.9. The parameter signals of the third PLC were the most different from the others, because the temperature and the illuminance were very high on the fourth floor. Keywords: humidity, illuminance, SCADA, temperature, wireless
