Data
acquisition can be defined as a system that serves to pick up, collect
and prepare the data, to process it to produce the desired data. Data
acquisition is a process of sampling of the physical real world
conditions and conversion of the resulting samples into digital numeric
values that can be manipulated by a computer. Components of the data acquisition system includes sensors that convert physical parameters to electrical signals. Signal conditioning circuitry used to convert sensor signals into a form that can be converted to digital kenilaiData Acquisition section consists of a voltage sensor arduino and PHP and MySQL database server.ARDUINOARDUINO
an electronic device system (electronic prototyping platform) with
software and hardware based on open-source so flexible and easy to use
for hardware and software. In
addition, the main advantages of ARDUINO is the number of developers
and users so much so that there are libraries of program code (code
library) and modules (peripheral) supporters in large numbers. These advantages facilitate novice users to further deepen the microcontroller world. Not only for beginners, professional practitioners proficient
electronics and advanced electronics enthusiasts also love ARDUINO
application in developing new electronic equipmentVOLTAGE SENSORA voltage sensor that is used is the usual voltage divider for DC
voltage connected to pin A2 ARDUINO, to an AC source using additional
circuit voltage riser so that no negative voltage so that the voltage at
A1 ARDUINO pin voltage is above ground.SERVER PHPIn
the creation of websites in this thesis, using Dreamweaver and web
server software XAMPP version 1.6.4 using the programming language PHP
and Mysql. In view website there will be some menu items such as Practice, Registration, Contacts and Log. Menu
lab practicum are active in the first semester and to add - remove the
lab module, on the menu of this practicum for students used to take
measurements for each of the existing lab module. Registration menu is used for students to register and see the group practicum. Contacts
menu is used to contact the site admin manager of the Website and the
last menu is the menu login This menu is used for professors, assistants
or students in accordance with the access rights.
