Most of these leaks is a small leak that is invisible to the naked human eye. The situation is often unknown Oleg customer taps, and impressed underestimated. Surely it was not deliberate by the customer, and will have an impact on water wastage and cost overruns water bill for the customer, as well as detrimental to customers. Therefore, to facilitate the detection of water leaks on customers, especially leaks are not visible to the naked eye, it is a tool designed to detect and protect the leak. This tool is called Detection of water leaks on customer taps using arduino uno, which has a main component arduino uno and sensors water flow, sensor water flow reading speed of the plumbing, the voltage generated will be even greater when the pressure in the big pipes and taps in a closed state , and vice versa. When the microcontroller receives data from sensors, microcontroller will process and store data and will display on the LCD.idTeknik ElektronikaElektronikaTeknik Dan Ilmu Yang BerkaitanSensorThesis
