Smart Water Management System for an Apartment

Water is an essential requirement for all living things. With the exponential growth of the human population, the need for water resource conservation is becoming increasingly important. Many water management systems have been proposed in the past. The pursuit of a smart water management system is gaining ground with the advent of the Internet of Things (IoT). This project aims at designing and implementing a smart water management system based on IoT for an apartment. The main requirements of the system are low cost, effectiveness and reliability. The project comprises of monitoring the different parameters with regards to water management and transmitting the data to a smartphone. Various parameters such as water level and flow rate are measured using appropriate sensors. The in-built Wi-Fi connection capability of the NodeMCU microcontroller is used to transmit the data to the Blynk application dashboard. The system is also designed to alert the user on his smartphone in case any fault such as low water level or water leakage is detected. A solenoid valve has also been implemented in the system to allow the user to control the flow of water in case of emergency. Furthermore, the system includes an LCD and buzzer so that the system can still be usable in case there is no WIFI connection.
