Arduino Water Level Meter

For my next big project automated plant watering system i was in need of having water level meter.

Arduino water level meter.

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 esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. In this project two circuits are used. I was choosing from contact and contactless methods of measuring fluid level in tank.

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

This project is wireless so it is easy to install and it can work up to 100 meters. 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 simple but useful project based on arduino nano. Also it can be used for your schoo.

The transmitter circuit makes use of an ultrasonic sensor to measure the water. Download circuit diagram and programming. 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. Measuring water level with ultrasonic sensor.

Check out the schematic prototype and video below. The water percentage is calculated and displays in the lcd. Thus the arduino water level indicator helps in preventing wastage of water in overhead tank. The lcd in the receiver unit displays the water level as a long bar.

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. A transmitter circuit and a receiver circuit. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.

Hc sr04 ultrasonic sensor interfacing distance measuring using arduino. Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi. Contact methods are resistive method capacitive and inductive.
