Abstract

This research would be the early stage in saving and managing energy, especially electrical energy in a miniature. The research has been done in the assembly of components, namely temperature, humidity, lighting and electric active power sensors, where they were equipped by 4-20 mA transmitters. These transmitters entered to the four channel analog module of programmable logic controller (PLC). From the PLC, using a router, the signals were transmitted to the computer in wireless remotely. Thus, besides the parameter quantities could be read in the panel, they also could be read in the computer in an online wireless remotely. Based on the testing results, for the humidity 58-60% in range, the error between the site display and PLC in the computer was only 0.3-0.4%, and for the temperature 28- 30oC, the error between the site display and PLC in the computer was only 0.2-0.3oC. The error of active power depended on the power itself. For example, the rating load of 25 and 100 watts, the remote display were 23 and 96 watts respectively. While, the time for signal transmission was under 0.1 second.
