Realisasi Sistem Switch Lampu Penerangan Ruangan Otomatis Untuk Meningkatkan Efisiensi Energi Listrik

Penghematan energi listrik sangat bergantung pada perilaku dan kesadaran manusia. Sekitar 80% keberhasilan kegiatan konservasi energi ditentukan oleh faktor manusia, sedangkan 20% lagi bergantung teknologi dan peralatan. Salah satu solusi alternatif dalam permasalahan ini adalah menerapkan sistem otomasi sehingga secara otomatis menghidupkan dan mematikan lampu ruangan dengan mendeteksi keberadaan manusia di dalam ruangan. Dalam penulisan ini melakukan realisasi rancangan  agar dapat dimanfaatkan oleh masyarakat sebagai fitting ekstensi otomatis dalam upaya penghematan daya listrik. Penelitian ini juga membandingkan disipasi daya yang timbul saat lampu tidak menyala dengan lampu sensor gerak yang ada di pasaran.  Realisasi rancangan terdiri dari dua sistem yaitu, menggunakan sensor PIR terintegrasi pewaktu NE555 dan sensor PIR terintegrasi mikrokontroler Atmega 8 SMD. Hasil yang dicapai adalah, disipasi daya lampu sensor gerak  type LED di pasaran adalah 6,2 Watt, lampu penerangan ruangan otomatis terintegrasi pewaktu IC555 lebih efisien 79,26% dibandingkan lampu sensor gerak di pasaran, lampu penerangan ruangan otomatis terintegrasi mikrokontroler atmega 8 lebih efisien 60,39% dibandingkan lampu sensor gerak di pasaran.

Double smart energy harvesting system for self-powered industrial IoT

312 p. 335 p. (confidencial)Future factories would be based on the Industry 4.0 paradigm. IndustrialInternet of Things (IIoT) represent a part of the solution in this field. Asautonomous systems, powering challenges could be solved using energy harvestingtechnology. The present thesis work combines two alternatives of energy input andmanagement on a single architecture. A mini-reactor and an indoor photovoltaiccell as energy harvesters and a double power manager with AC/DC and DC/DCconverters controlled by a low power single controller. Furthermore, theaforementioned energy management is improved with artificial intelligencetechniques, which allows a smart and optimal energy management. Besides, theharvested energy is going to be stored in a low power supercapacitor. The workconcludes with the integration of these solutions making IIoT self-powered devices.IK4 Teknike

Energy Efficiency: A Guide to Current and Emerging Technologies. Volume 1: Buildings and Transportation

Energy Efficiency: A Guide to Current and Emerging Technologies is the fourth and final major CAE project, carried out between 1993 and 1996. It was published in 1996 in two volumes – Volume 1, Buildings and Transportation, dealing with domestic, commercial and industrial buildings and transport, and Volume 2, Primary Production and Industry, dealing with primary production, food processing, forestry processing and manufacturing and minerals. Volume 2 also includes a section on general energy efficiency technologies. The focus of the two volumes is on energy efficiency technologies currently available and applied overseas, but not widely used in New Zealand, and on emerging technologies that are likely to prove practical for New Zealand within the next decade. While the emphasis is on New Zealand experience, the technologies discussed have application worldwide. Barriers that might restrict the use of individual technologies are also discussed
