Arduino Water Level Meter

In this project two circuits are used.

Arduino water level meter.

The water percentage is calculated and displays in the lcd. Measuring water level with ultrasonic sensor. 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.

The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. Project tutorial by newmc. The lcd in the receiver unit displays the water level as a long bar. Hc sr04 ultrasonic sensor interfacing distance measuring using arduino.

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. I was choosing from contact and contactless methods of measuring fluid level in tank. Also it can be used for your schoo.

For my next big project automated plant watering system i was in need of having water level meter. This project is wireless so it is easy to install and it can work up to 100 meters. 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. This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator.

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. Download circuit diagram and programming. It is a cheap and intelligent way to control your water tank levels. The ping sensor measures distance using sonar.

Thus the arduino water level indicator helps in preventing wastage of water in overhead tank. 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. In the program the distance values are adjusted for a water tank of 1 meter height. This simple but useful project based on arduino nano.

A short message like low normal full or. Contact methods are resistive method capacitive and inductive. The transmitter circuit makes use of an ultrasonic sensor to measure the water.
