Smart Water Billing System for Apartments

This article presents an electronic water billing system for people who live in apartments. Nowadays, a common water tank is shared among people in the apartment or kept as a separate water tank for each house. Many problems arise in these systems, such as improper water billing and the lack of a proper data management system to maintain data such as the quantity of water consumed by each person in the apartment and the corresponding cost of water consumed. In order to address these issues, the proposed system continuously measures the amount of water consumed by an individual’s home using a water flow sensor. If the consumed water quantity exceeds a particular value, the Arduino microcontroller calculates the corresponding amount of that extra water. At the same time, a buzzer will ring and an alarm will blink continuously to indicate the consumer’s extra consumption of water. The data, like the quantity of extra water consumed and charges for that extra water, is stored in a cloud using the Wi-Fi module. This cloud will act as a data management system and the advantage of using cloud storage is the increased security of stored data and the ability to access that data anywhere in the world at any time.
