PENERAPAN MIKROKONTROLER, SENSOR PHOTODIODE DAN ULTRASONIC PADA PROTOTIPE PENGGANTI AIR OTOMATIS PADA AKUARIUM

Abstract

The development of information technology has grown rapidly so as to make progress in various fields, one of which is in the field of electronics. With the development of the digital electronics, also produces a variety of ready-made hardware products consisting of microcontroller circuit. One other development of digital electronics is the development of sensor technology. By combining the microcontroller circuit with sensor technology, it is possible to design a device to automation-specific. Based on the above, the authors are encouraged to design a prototype that serves as a replacement tool automatically at the aquarium water using a microcontroller by combining technology and ultrasonic sensors photodiode. In order to help people to reduce interference, ease the workload and save time in doing a job. Keywords : Microcontroller, Photodiode Sensors, Ultrasonic, Automatic Water Substitute
