System of smart detection and control to electrical energy for saving of electrical energy consumption

Public campus has a mandate to saving of electrical energy. Electrical energy consumption is often wasteful in building. There tendency by user. Electronic equipment still turn on at idle time. Only few students want off the and shut down computer. Saving not only time but it can be improved into operational hour. It depending or hours, depends human presence. Implementation supported frugal behavior technology. In this study, we name system smart detection control (Sisdece). This consist hardware software. Hardware applies passive infrared sensor (PIR) sensor, wireless network (WSN), microcontroller ESP32, access point, relay. Software use C++, hypertext preprocessor (PHP), markup language (HTML) android studio. Result measurement been done month during November 2020. Average saved 12.51 kWh total 105.86 kWh. Comparison 11.81%. significant reduction bill. The result expected as benchmark management Politeknik Negeri Medan (POLMED).
