In this tutorial you will learn how to make a water level monitoring system using arduino ultrasonic sensor and some leds.
Ultrasonic water tank level meter arduino.
The technique behind this idea is easy to understand.
To check the water level ultrasonic hc sr04 is the distancesensor.
The circuit automatically switches the motor off when the tank is full.
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.
Water meter sensor ultrasonic water tank liquid depth level meter sensor with temperature display for indoor water tank up to 100m 2 2 out of 5 stars 5 74 29 74.
This is a beginner s level project explaining the basics.
The ping sensor measures distance using sonar.
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 idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used.
This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.
The leds are used to show the percentage of water available in the water tank.
This project is a about a fully functional water level controller using arduino and cayenne.
If the water level remains above 50 of the full capacity of the tank you should see the green light from the status.
Ultrasonic method is similar to radar.
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.
Instead of radar wave we are sending ultrasonic wave.
This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced.
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.
The ultrasonic sensor reads the distance from the bottom of the tank using ultrasonic wave transmission by the formula distance speed time.
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.
The project under discussion has the capability to checkthe water level and also send the data over wifi.
