Abstract

Smart Classroom Using LabVIEW is a system that created to minimize the usage of the energy and study the energy saving by implement the sensor to the project. Sensors will switch on/off the classroom power supply when detect the appearance of students. Besides that, another function of the project is by using the time arrangement to control the power supply of the classroom. The main objectives of the project are to prevent the energy waste to save our environment, to save the electricity cost of university and tax payers. LabVIEW had been used for this project and design front panel of the sensor mode and schedule mode. The front panel of the program is friendly use to most lecturers because easy to understand by just select the mode. When using the schedule mode, lecturers need to arrange the time table in the program and the system will switch on and off the power supply with the time given in the program. When lecturers switch the system to sensor mode, the sensor will start send the signal to DAQ whether there have any appearance in the classroom or not, if yes, the sensor will come out with 1.4VDC output signal to DAQ analog port and switch on the power supply by digital port. If no student presence, the output will remain off mode. DAQ is a data acquisition that used in the system to interface between the PC and hardware; it is a very useful device that can use for multipurpose measurement. For further application, this system can use for commercialize with home, office, classroom and so on.
