Abstract: Urinary tract disorders and lower urinary tract dysfunctions are common health concerns that require accurate assessment of urine flow characteristics for early diagnosis and effective treatment. Conventional uroflowmetry systems used in hospitals are often expensive, bulky, and require dedicated clinical infrastructure, making them less accessible in remote and resource-limited environments. The main objective of this invention is to develop a portable smartphone-based uroflowmeter that is compact, affordable, non-invasive, and easy to operate for real-time urinary flow monitoring. The sensing module of the proposed system is based on a load cell sensor integrated with an HX711 amplifier module, which continuously measures the weight of urine collected in a container during the voiding process. The load cell converts the applied force into electrical signals, and the 1-IX711 amplifies and converts these signals into digital data for accurate measurement. The primary controller of the system is the NodeMCU microcontroller, which acquires sensor data, processes flow measurement algorithms, and calculates important uroflowmetry parameters such as urine volume, flow rate, maximum flow rate (Qmax), average flow rate (Qavg), and voiding time in real time. The device further incorporates wireless communication through Wi-Fi, enabling seamless transmission of processed data to a smartphone or web-based interface for instant visualization and graphical analysis. A urine collection container, compact sensor platform, rechargeable power supply, and portable enclosure ensure ease of operation in hospitals, clinics, home healthcare, and rural medical camps.
