Dual Mode Smart Water Supply Measurement and Monitoring System for Over Head Tanks (OHTS)

The Dual Mode Smart Water Supply Measurement and Monitoring System is designed to efficiently track and manage water levels in Overhead Tanks (OHTs) using advanced sensor technology and automation. An ultrasonic sensor monitors the water level, while a water flow sensor accurately measures water consumption. The system is controlled by an Arduino microcontroller, with real-time data displayed on an LCD screen and transmitted to ThingSpeak via NodeMCU for remote monitoring. A GSM module sends alerts in abnormal conditions, ensuring timely intervention. Additionally, the system features an automated water supply mechanism where a certain amount of water is provided free of charge, after which a tiered billing system applies charges based on usage. The generated bill is then sent to users via SMS notifications. A relay-controlled water pump automatically activates when water levels drop below a set threshold, ensuring an uninterrupted water supply while minimizing wastage. By integrating IoT, automation, and real-time billing, this smart solution enhances water management efficiency, promotes fair usage, and ensures sustainability in water distribution.
