Ultrasonic Water Tank Level Meter Arduino

Hc sr04 ultrasonic sensor interfacing distance measuring using arduino in the program the distance values are adjusted for a water tank of 1 meter height.

Ultrasonic water tank level meter arduino.

After the sensor is triggered it sends out sound waves to the surface of the water liquid content which obstructs the signal at whichever level and echoes back to the sensor. We made water level meter with arduino platform we used arduino mega2560 but any arduino will work. The project under discussion has the capability to checkthe water level and also send the data over wifi. In this tutorial you will learn how to make a water level monitoring system using arduino ultrasonic sensor and some leds.

This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced. This is a beginner s level project explaining the basics. The ultrasonic sensor reads the distance from the bottom of the tank using ultrasonic wave transmission by the formula distance speed time. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.

The 1 meter height is divided into 3 reference levels of water at quarter half and three quarter depth of the tank taken in centimeters. Instead of radar wave we are sending ultrasonic wave. If the water level remains above 50 of the full capacity of the tank you should see the green light from the status. An ultrasonic well above human hearing pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return.

The ultrasonic sensor sends out an ultrasonic pulse waits for it to come back and depending on the time between the two events the microcontroller can then calculate the distance between the sensor and the water surface. The circuit automatically switches the motor off when the tank is full. The ping sensor measures distance using sonar. There is no specific method to checkthe level of the water.

To check the water level ultrasonic hc sr04 is the distancesensor. The cayenne app displays the level of water in the tank and switches the motor on when the water level goes below a predetermined level. The idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used. Ultrasonic method is similar to radar.

The leds are used to show the percentage of water available in the water tank.
