Contact methods are resistive method capacitive and inductive.
Arduino water level meter.
Also it can be used for your schoo.
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.
Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi.
This simple but useful project based on arduino nano.
You can use only the leds if you want the lcd is optional.
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.
A short message like low normal full or.
The transmitter circuit makes use of an ultrasonic sensor to measure the water.
It is a cheap and intelligent way to control your water tank levels.
This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.
The water percentage is calculated and displays in the lcd.
Hc sr04 ultrasonic sensor interfacing distance measuring using arduino.
This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator.
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 project is wireless so it is easy to install and it can work up to 100 meters.
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.
A transmitter circuit and a receiver circuit.
Check out the schematic prototype and video below.
In the program the distance values are adjusted for a water tank of 1 meter height.
I was choosing from contact and contactless methods of measuring fluid level in tank.
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.
In this project two circuits are used.
Measuring water level with ultrasonic sensor.
The ping sensor measures distance using sonar.
The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board.
