Automated Tank Water-level Monitoring system (Overflow and Underflow) using Sensors

Abstract

In daily life, water supply is very necessary for every activity and functions as water consumption. In urban areas where water supply is regulated for a specific time, a person must be present at that specific time to turn on their water pumps and store water in their water storage tank, and also the water tank is empty (the water level is below the tank ). If they are not present at that time, they have to go through hardships caused by a lack of water. It intelligently (without the need of any person) turns on the motor when the water is supplied and turns off the motor when the tank is filled. Nowadays, more and more people turn on the motor and forget to turn it off, causing waste of water and electricity due to overflowing of the water tank. The system is designed using an ultrasonic sensor, an automatic switching module, an IOT based ultrasonic sensor, and a pumping machine for automatic water filling switching. When using an ultrasonic sensor, an ultrasonic transmitter is mounted on the top of the tank, which sends an ultrasonic pulse down into the tank. The motor will remain on and fill the tank until another water sensor in the tank signals the ultrasonic sensor that the tank is full. When the tank is full, the ultrasonic sensor with the received signal will automatically turn off the water pump motor. When the tank is empty, the ultrasonic sensor with the received signal automatically turns on the water pump motor. This eliminates the need for a person to be physically present in time to turn on/off the water pump motor. It will be used, people will enjoy the water supply without worrying about spilling water and wasting electricity
