Arduino Water Level Meter

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.

Arduino water level meter.

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. Project tutorial by newmc. This project is wireless so it is easy to install and it can work up to 100 meters. The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board.

One output gpio pin is directly connected to the water level sensor and sends a 3 3 v signal to the sensor with a duration of just 200 milliseconds. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. A short message like low normal full or. Check out the schematic prototype and video below.

This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator. It is a cheap and intelligent way to control your water tank levels. This simple but useful project based on arduino nano. You can use only the leds if you want the lcd is optional.

The lcd in the receiver unit displays the water level as a long bar. The ping sensor measures distance using sonar. Contact methods are resistive method capacitive and inductive. In this project two circuits are used.

A transmitter circuit and a receiver circuit. Hc sr04 ultrasonic sensor interfacing distance measuring using arduino. For my next big project automated plant watering system i was in need of having water level meter. Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi.

In the program the distance values are adjusted for a water tank of 1 meter height. 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. Also it can be used for your schoo. I was choosing from contact and contactless methods of measuring fluid level in tank.

The water percentage is calculated and displays in the lcd. The transmitter circuit makes use of an ultrasonic sensor to measure the water. Download circuit diagram and programming.
