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.
