Rancang Bangun Sistem Penyiraman Tanaman Secara Otomatis Menggunakan Sensor Suhu LM35 Berbasis Mikrokontroler Atmega8535

During the time, plants watering is done manually. But, sometimes we don’t have more time watering the plants. Therefore, we need a tool that can help us to do that. A tool as system that can work automatically. By using this tool, we hope watering plants can be done in the correct moment and time. This research is done by developing an automatically plants watering system using microcontroller ATMega8535 as the main controller and suhue sensor LM35. This system also uses Real Time Clock (RTC) 1307 as timer, and Liquid Crystal Display (LCD) as display. The plants watering system can watering the plants automatically. When the detected temperature comes into the category limit that has been determined, system can work automatically watering the plants. LCD will displays real time and air temperature value surroundings the plants

Monitoring dan Pengendalian Level Cairan Jarak Jauh Berbasis WEB

Abstract{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 pag
