核心概念
An IoT-based system to continuously monitor water level, flow, and gas levels in drainage pipes to detect and alert authorities about water-logging issues in Dhaka, Bangladesh.
摘要
The content discusses the problem of water-logging in Dhaka, Bangladesh, and proposes an IoT-based solution to address it.
Key highlights:
Dhaka, the capital of Bangladesh, faces severe water-logging issues due to heavy rainfall, clogged drainage pipes, and poor maintenance of the sewerage system.
The proposed system uses IoT sensors to continuously monitor water level, flow, and gas levels in drainage pipes. This data is sent to a central database and displayed on an operator dashboard.
The system can detect potential water-logging issues by analyzing the sensor data and send alerts to the nearest maintenance office.
The hardware prototype includes a Node MCU microcontroller, GPS module, water flow sensor, ultrasonic sensor, and gas sensor.
The system uses a four-layer architecture: perception layer (sensors), network layer (wireless communication), data link layer (database), and application layer (operator dashboard).
The simulation results show the system can effectively detect and alert about water-logging problems in the drainage system.
統計資料
The average annual rainfall in Bangladesh is 200 mm per year.
Dhaka has faced more rainfall than ever before in recent years.
引述
"Water-logging is a major problem that many cities face. It is quite common in cities of third world countries, especially those countries that are bestowed with the season of monsoon like Dhaka, Bangladesh."
"Lack of basic education and sanitation sense has caused people to clog up drainpipes. Criminals are also to blame for water-logging; they are illegally encroaching the waterbodies that serve the city."
