Monitoring Dan Pengendalian Level Cairan Jarak Jauh Berbasis WEB

摘要

{This research designs a remote monitoring and controlling water level via Internet using a Web-based programming language Hypertext Preprocessor (PHP). The system utilize micro controller and data communication using Universal Serial Asynchronous Receiver-Transmitter (USART). The ultrasonic sensors is used to detect water lever and send the data from sensor to the microprocessor. Then the micro controller sends the data to serial port via USART communications. Furthermore the PHP program reads data in serial port and displays water level through a web page.
