Water Level Indicator Using Arduino & Ultrasonic Sensor
Water Level Indicator Using Arduino
Wireless Water Level Indicator Using Ultrasonic sensor & Arduino is an amazing and very useful project. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. This project can be further enhanced to control the water level in the tank by turning it ON, when the water level is LOW, and turning it OFF when the water level is HIGH. Thus, the Arduino water level indicator helps in preventing wastage of water in overhead tank. This project is wireless so, it is easy to install and it can work up to 100 meters.
In this project two circuits are used: a transmitter circuit and a receiver circuit. The transmitter circuit makes use of an ultrasonic sensor to measure the water level in terms of distance. This data is sent to the receiver circuit using RF communication. The water level is shown in terms of percentage on a 16×2 LCD module, which is connected to receiver circuit.
In the project two circuits are used, First is the transmitter and second is the receiver. An Ultrasonic sensor is used in the transmitter circuit, which measures the distance of water level from the upper point of the bottle or Tank. The distance is measured in centimeters and sent to receiver circuit using RF communication.
Receiver circuit receives the data from transmitter circuit and converts it in terms of the percentage and shows on LCD.
Ultrasonic sensor has two openings, one is Trigger and the other is Echo. Trigger makes high frequency sound waves. These sound waves are passed through the tank from top to bottom. The sound waves hit the water and are reflected back in the form of Echo waves. The Echo opening receives the Echo waves. The water level sensor Arduino measures the time between Echo and Trigger. This traveled distance is directly proportional to the time.
