Arduino Water Level Meter

This project is wireless so it is easy to install and it can work up to 100 meters.

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. The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. Project tutorial by newmc. Hc sr04 ultrasonic sensor interfacing distance measuring using arduino.

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 transmitter circuit makes use of an ultrasonic sensor to measure the water. The water percentage is calculated and displays in the lcd. It is a cheap and intelligent way to control your water tank levels.

Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi. Thus the arduino water level indicator helps in preventing wastage of water in overhead tank. 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. Contact methods are resistive method capacitive and inductive.

The lcd in the receiver unit displays the water level as a long bar. In this project two circuits are used. For my next big project automated plant watering system i was in need of having water level meter. This simple but useful project based on arduino nano.

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. You can use only the leds if you want the lcd is optional. In the program the distance values are adjusted for a water tank of 1 meter height.

This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator. Download circuit diagram and programming. A transmitter circuit and a receiver circuit. I was choosing from contact and contactless methods of measuring fluid level in tank.

Measuring water level with ultrasonic sensor. Check out the schematic prototype and video below. Also it can be used for your schoo.
