Arduino Water Level Meter

The ping sensor measures distance using sonar.

Arduino water level meter.

Also it can be used for your schoo. Check out the schematic prototype and video below. You can use only the leds if you want the lcd is optional. This meter sense the water level using an ultrasonic sensor placed under the lid of the tank and sends the data via a wireless transmitter to the receiver unit.

Project tutorial by newmc. This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator. The lcd in the receiver unit displays the water level as a long bar. This simple but useful project based on arduino nano.

Download circuit diagram and programming. A short message like low normal full or. In this project two circuits are used. Contact methods are resistive method capacitive and inductive.

The water percentage is calculated and displays in the lcd. A transmitter circuit and a receiver circuit. Thus the arduino water level indicator helps in preventing wastage of water in overhead tank. Here is a tested arduino project that uses 3 sensor probes as water level indicator with 3 leds and one lcd display a simple controller that turns on a motor when the water has reached the desired level the highest in our case.

This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. The transmitter circuit makes use of an ultrasonic sensor to measure the water. 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. 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. For my next big project automated plant watering system i was in need of having water level meter. This project is wireless so it is easy to install and it can work up to 100 meters. Measuring water level with ultrasonic sensor.

The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. It is a cheap and intelligent way to control your water tank levels. 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.
