Abstract

The fundamental right to inhabit a clean and salubrious environment is universally acknowledged. Many developing nations, including Bangladesh, grapple with the recurrent issue of flooding caused by obstructed drainage systems, which in turn gives rise to unsanitary conditions. This dire situation can lead to health complications as the atmosphere becomes contaminated by sewage gases. Stagnant water on roadways serves as a breeding ground for the proliferation of Aedes mosquitoes, a major contributor to the escalating health crisis. Detecting these drainage issues manually is arduous, and often, the mess only becomes apparent once the drains are already blocked, flooding entire areas. To address this critical problem, we propose the development of an advanced warning system that employs GSM (Global System for Mobile Communications) and IoT (Internet of Things) technologies. Our system is designed to preemptively avert such incidents, protecting public health. Key components of our system include MQ135 and MQ2 gas sensors to detect sewage gas, an ultrasonic sensor for gauging sewage water levels, and a flow sensor to monitor the rate of water flow. When the water level in the drains surpasses a predetermined threshold, our system will trigger an alert mechanism, sending real-time notifications via GSM to the relevant authorities. These alerts will specify the areas in need of immediate attention and provide precise geographic coordinates using GPS data. Additionally, both government agencies and the general public will have access to real-time data through an online platform, such as Thingspeak. Importantly, our system allows users to finetune the threshold values according to their preferences. By ensuring that authorities are promptly notified and by offering real-time data accessibility, our system aims to enhance the overall well-being of the community, enabling residents to lead healthier lives.
