DESIGN OF CONTROL AND MONITORING SYSTEMS ELECTRONIC EQUIPMENT ENERGY IN CLASSROOMS WEB-BASED

Abstract

Classroom is a place that use by student to learn. Each classroom equipped by electrical equipmentand tool including 4 lamps and 2 fans. When learning activities is over in some classroom, lamps and fans still on. The cause of this condition is dueto manual control, the result is electricity to be wasteful. As a result, electricity supply is run outbefore one month use and it can obstruct the learning activitiesif the power goes out. The aim of theresearch is to build a system that able to controls electricity equipment in the classroom and make a monitoring power consume remotely so can be effective and efficient. The system design is use prototype method that is a design software technic, while in designing web, with Data Flow Diagram (DFD) and Entity Relationship Diagram (ERD). Control design and monitoring use Raspberry Pi 3 B+ as microcontroller and web as interface user media. Relayconnected with raspberry pi through General Purpose Input Output (GPIO) as automatic switch. USB Converter serial as interface for communicating raspberry pi with PZEM-004T module as current, voltage and power reader. The result of the study Can control and monitor the use of power consume in electrical equipment remotely web based. The system is completed by daily report of power consumeand warning notification on the web when kWh almost running out. This research is useful in preventing wasting electricity and running outof electricity while learning is in progress.
