Arduino Water Level Meter

This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.

Arduino water level meter.

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. I was choosing from contact and contactless methods of measuring fluid level in tank. The transmitter circuit makes use of an ultrasonic sensor to measure the water.

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. 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. Project tutorial by newmc. 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. Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi. A transmitter circuit and a receiver circuit. The ping sensor measures distance using sonar.

In this project two circuits are used. 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. Thus the arduino water level indicator helps in preventing wastage of water in overhead tank.

The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. Measuring water level with ultrasonic sensor. Check out the schematic prototype and video below. In the program the distance values are adjusted for a water tank of 1 meter height.

Download circuit diagram and programming. 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. You can use only the leds if you want the lcd is optional. A short message like low normal full or.

Contact methods are resistive method capacitive and inductive. Also it can be used for your schoo. The water percentage is calculated and displays in the lcd.
