PERANCANGAN DAN IMPLEMENTASI ALAT UKUR KUALITAS AIR MENGGUNAKAN METODE NEFELOMETRIK
Abstract
Turbid warter is one of the characteristics of unclean water and unhealthy. Importance of water clarity to humans at this time then designed a device that could measure water quality using a LDR sensor, where the sensor can detect light from a diode light levels. LED penetrating the water, it will be detected water quality. Microcontroller in the system that became controlleris arduino uno. Out of this toolis the percentage rate that water quality will be displayed on the LCD. Testing water quality measuring instrument is using nefelometric. System testing is done by detecting changes in the level of water quality in five sampel of bottled water, drinking water processed two and three wastewater. The results are not clear, the higher the level of water or less clear water, the sensor output voltage is also higher.
