Arduino Water Level Meter

Measuring water level with ultrasonic sensor.

Arduino water level meter.

The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. I was choosing from contact and contactless methods of measuring fluid level in tank. This project is wireless so it is easy to install and it can work up to 100 meters. 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.

Download circuit diagram and programming. Check out the schematic prototype and video below. It is a cheap and intelligent way to control your water tank levels. 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.

In the program the distance values are adjusted for a water tank of 1 meter height. 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. 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. Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi.

In this project two circuits are used. A transmitter circuit and a receiver circuit. This simple but useful project based on arduino nano. A short message like low normal full or.

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. Hc sr04 ultrasonic sensor interfacing distance measuring using arduino. The ping sensor measures distance using sonar. For my next big project automated plant watering system i was in need of having water level meter.

Also it can be used for your schoo. The transmitter circuit makes use of an ultrasonic sensor to measure the water. The water percentage is calculated and displays in the lcd. Project tutorial by newmc.

This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. 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.
