The working of the complete water level indicator project is shown in below block diagram. <>
This module is designed mainly for the DIY hobbyist and provide them a low-cost and easy-to-use water level detection scheme. When empty water level reaches at distance about 30 cm then Arduino turnsON the water pump by driving relay. After it we need to calculate water level. Upload the following sketch on Arduino by pressing the "Run on Arduino" button and then press the "Connect" button to start serial communication. Finally, connect the S (Signal) pin to the A0 ADC pin on your Arduino.

To program Arduino forwater level controller, first we define all the pin that we are going to use in the project for interfacing external devices like relay, LCD, buzzer etc. 4 years ago Thus the time to reach obstacle is just half the total time taken. To see it sense water, you can take a glass of water and slowly put the sensor in it. Ultrasonic sensor HC-SR04 is used to measure distance in range of 2cm-400cm with accuracy of 3mm. First you need to supply power to the sensor. This time we just need to add some LEDs. So we have to only calculate its traveling time of both sounds means outgoing time and returning time to origin after striking on any obstacle. The more water the sensor is immersed in, results in better conductivity and will result in a lower resistance. You should see a value 0 when the sensor is not touching anything. My analog values from this procedure are: As you can see the sensor resolution decreases as the water reaches the maximum level. Now we can convert this water level in to the percent of water, and can display it on LCD. hj} 09Jo

Once you get a good handle on these readings, you can use them as threshold if you intend to trigger an action.
