Urinary tract infection or UTI is a disease that can be suffered by anyone of any age and sex. Urinary tract infections can be identified from several important parameters, namely difficulty urinating, the amount of urine is small and the urine comes out slowly. To find out about urinary tract infections, it is needed innovation uroflowmetry that can measure the volume of urine, as well as measuring urine discharge which is designed more practically using a Bluetooth module so that the results of the examination can be displayed on a laptop. In this uroflowmetry innovation for measurement of urine discharge and urine volume the author uses the YF-S401 sensor with the output of a pulse signal which will be converted to mL / min. The author uses Arduino UNO with IC ATMega328p as a data processing and HC-05 bluetooth module as a wireless data sender. In displaying the results of the examination the author uses delphi7 application with a graphical and numeric display. The results of volume testing obtained the average value of error when measuring 100 mL volume is 0.02%, when measuring 200mL volume is 0.014%, when measuring 300mL volume is 0.032%, when measuring 400mL volume is 0.0075 and at when measuring 500mL volume is 0.004mL. Bluetooth testing results obtained connection distance between the HC-05 bluetooth module with a laptop <5m.
