As we know an Arduino is a Development board which operates with 5V and hence we need a switching driver circuit for the Solenoid to turn it on and off. That is when the Valve is turned on it will consume about 700mA to keep the valve turned on. The solenoid valve used in this project is a 12V valve with a maximum current rating of 1.2A and a continuous current rating of 700mA. The complete circuit diagram for Arduino based water Dispenser is shown below Learn more about using Ultrasonic sensor with Arduino here. So we will write an Arduino program which always checks if any object is placed near the tap, if yes then the solenoid will be turned on and wait till the object is removed, once the object is removed the solenoid will turn off automatically thus closing the supply of water. A solenoid valve will be used to control the flow of water, which is when energised the water will flow out and when de-energised the water will be stopped. We will use a HCSR04 Ultrasonic Sensor to check if any object such that the glass is placed before the dispenser. The Concept behind the Automatic Water Dispenser is very simple.

So in this project we will build a Automatic Water Dispenser using Arduino and a Solenoid valve that can automatically give you water when a glass is placed near it.

If we replace all the manual taps with a smart one that opens and closes on its own automatically not only we can save water but also have a healthier lifestyle since we don’t have to operate the tap with our dirty hands. So what can be done to stop this? As always the answer, for this, lies with improvement in technology. It might not appear big at the first time, but if your tap dripped a drop of water once every second it would take only about five hours for you to waste one gallon of water, that is enough water for an average human to survive for two days. At one hand there are already minor disputes among nations and states for sharing river water on the other hand we as humans waste a lot of drinking water due to our negligence. With rise in population, pollution and climate change, it is expected that by as soon as 2025 we will experience perennial water shortages. Now we can change this water level into the % of water and can display it on LCD.About 71% of earth is covered with water, but sadly only 2.5% of it is drinking water. And we will receive the water level distance. Then we can measure the water level by subtracting the resulting distance coming from ultrasonic from the total length of the tank. Now we will calculate the total length of the water tank. After it, it is important to measure the water level. With the help of this method, we get the distance from the sensor to the water surface. Where the speed of sound is about 340m per second. so we can measure distance with the help of the formula:ĭistance= (travel time/2) * speed of sound We know that the speed of sound is around 340 m/s.

Arduino interprets the time between triggering and received ECHO.

First of all, we require to trigger the ultrasonic sensor module to share the signal by using Arduino and then wait to receive ECHO. We have utilized an Ultrasonic sensor module that sends the sound waves in the water tank and recognizes the reflection of sound waves that is ECHO. Thus the distance of the obstacle from the sensor is generally estimated by the formula given as The signals after striking an obstacle it will return back and are captured with the help of the receiver. The sensor module includes an ultrasonic transmitter, receiver as well as control circuit. Ultrasonic sensor HC-SR04 is utilized to estimate distance in the range of 2cm-400cm with an accuracy of 3mm. The concept we have used here in our project where the water motor pump is automatically turned on when the water level in the respective tank becomes low.
