Abstract— Flooded underpasses lead to massive traffic jam, safety risk and mobility failure in the city during downfalls. The traditional pump houses use manual checkups and simple electric indicators which give very little information on pump operation and water level status. Here, this paper will provide a full Smart Underpass Pump System (SUPS) developed with an STM32 microcontroller, multi-sensor monitoring, SMS alerts on GSM, and a cloud-linked dashboard to provide real-time visualization. Systems incorporated to the system include two water level float sensors, a diesel tank float sensor, a YF-S201 flow sensor, a SW-420 sensor that verifies the pump is in operation through vibration, and a DS18B20 temperature sensor. An algorithm of vibration analysis using Windows can easily identify the ON/ OFF switching of the pump, water-level and flow-rate sensor identify the performance of a system under different load conditions. STM32 produces structured JSON telemetry sent over backend services to a MongoDB database allowing live graphs and logs to the Admin, Manager and Workman dashboards. A SIM800L GSM module is a type of module that will give instant SMS notifications whenever the pump is switched ON or OFF. It is tested in experiments with very reliable pump-state detection, a stable telemetry, a speedy SMS delivery, and the stable real-time dashboard performance. The proposed solution provides an affordable field deployable, practical, underpass management solution to the municipality.
