This document describes a smart water tank project that uses an ultrasonic sensor and Arduino to automatically control a motor based on water level. When the water level drops below a certain point, the ultrasonic sensor detects this and turns the motor on to refill the tank. When the water reaches a full level, the sensor turns the motor off. An intermediate level triggers a text message on a mobile phone via GSM modem to notify the tank is at 50% capacity. The system is designed to automatically regulate water levels in applications like hotels, factories and homes to efficiently control water pumps.

2. Abstract :
 This circuit is designed to determine the water level
especially in Water Tank.
 As the water level decreases from the particular level
then motor will automatically ON
 As the water level increases from the particular level
then motor will automatically OFF

3. Components:
 Following are the required components for
making water level indicator circuit:
1. Ardino Nano
2. UltraSonic Sensor
3. 5V DC battery
4. Connecting wires
5. DC Motor
6. Motor Driver
7. GSM Modem

4. Component Details:
 1.Ardino Nano :
 Arduino is an open-source project that created
microcontroller-based kits for building digital
devices and interactive objects that can sense and
control physical devices.
 2.Ultrasonic Sensor:
 Ultrasonic Sensors are widely used in Robo
projects for Distance measurement as well as
Obstacle detector

5. 3. Power Supply:
A DC power supply of about 5V is taken.
4.Connecting Wires:
Few connecting wires are used for connection in the
circuit.
5.DC Motor:
A motor is an electrical machine which converts
electrical energy into mechanical energy.

6. 6.Motor Driver :
Motor Driver is motor connection driver.
It provide power supply to motor.
7. GSM Modem:
GSM is a mobile communication modem; it is stands
for global system for mobile communication (GSM).

8. Working:
 The operation of this project is very simple and can be
understood easily. In our project “Smart Water Tank”
there are 3 main conditions:
 There is no water available in the source tank.
 There is ample amount of water available in the source
tank.
 So let us discuss on the more about these 3 conditions

9. Condition 1:Water is not
available
 When the tank is empty there is automatically motor
will on with the help of UltraSonic Sensor

10. When the tank is full then motor will
automatically
off with the help of UltraSonic Sensor

11. Condition 3:Intermediate levels
 Now as the water starts filling in the tank a conductive
path is established and it gives message on mobile
with the help of GSM modem Sensor.
 When tank is filled halfly then it gives msg that tank is
filled 50%

12. Application:
 Automatic Water level Controller can be used in Hotels,
Factories, Homes Apartments, Commercial Complexes,
Drainage, etc.,
 Automatic water level controller will automatically START
the pump set as soon as the water level falls below the
predetermined level (usually 1/2 tank) and shall SWITCH
OFF the pump set as soon as tank is full.
 Fuel level indicator in vehicles.
 Liquid level indicator in the huge containers in the
companies.
