Arduino Water Level Meter

Download circuit diagram and programming.

Arduino water level meter. The transmitter circuit makes use of an ultrasonic sensor to measure the water. In the program the distance values are adjusted for a water tank of 1 meter height. 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. Measuring water level with ultrasonic sensor.

The water percentage is calculated and displays in the lcd. The ping sensor measures distance using sonar. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi.

It is a cheap and intelligent way to control your water tank levels. 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. A transmitter circuit and a receiver circuit. Thus the arduino water level indicator helps in preventing wastage of water in overhead tank.

You can use only the leds if you want the lcd is optional. Check out the schematic prototype and video below. This simple but useful project based on arduino nano. The lcd in the receiver unit displays the water level as a long bar.

Project tutorial by newmc. In this project two circuits are used. 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.

Contact methods are resistive method capacitive and inductive. A short message like low normal full or. 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. 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.

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.
