Arduino Water Level Meter

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.

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. 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. 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. The lcd in the receiver unit displays the water level as a long bar. The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board.

Check out the schematic prototype and video below. In the program the distance values are adjusted for a water tank of 1 meter height. 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.

Project tutorial by newmc. 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. 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. 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.

In this project two circuits are used. 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. Measuring water level with ultrasonic sensor.

This simple but useful project based on arduino nano. Download circuit diagram and programming. You can use only the leds if you want the lcd is optional. A short message like low normal full or.

Hc sr04 ultrasonic sensor interfacing distance measuring using arduino. Also it can be used for your schoo. The water percentage is calculated and displays in the lcd.
