It is a cheap and intelligent way to control your water tank levels.
Arduino water level meter.
This simple but useful project based on arduino nano.
The transmitter circuit makes use of an ultrasonic sensor to measure the water.
I was choosing from contact and contactless methods of measuring fluid level in tank.
A transmitter circuit and a receiver circuit.
This project is wireless so it is easy to install and it can work up to 100 meters.
The lcd in the receiver unit displays the water level as a long bar.
This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator.
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 water percentage is calculated and displays in the lcd.
In the program the distance values are adjusted for a water tank of 1 meter height.
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.
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.

Measuring water level with ultrasonic sensor.
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.
Contact methods are resistive method capacitive and inductive.
Also it can be used for your schoo.
Check out the schematic prototype and video below.
Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi.
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.
The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board.

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.
