This study aims to develop a non-contact uroflowmeter. The sensor unit consists of four non-contact matrix temperature sensors, a multiplexer and a built-in microcomputer. The sensor unit was installed in an existing toilet. Using pure water to pseudo-urine, we examined both change of room temperature and pseudo-urine temperature. The conversion coefficient for estimating pseudo voided volume was affected by both temperatures. Next, we studied how the sitting down on the toilet and flushing influenced the estimated urine volume with subjects. The estimated volume from the temperature sensor showed a good relationship to weight difference before and after the urination.
