Arduino Water Level Meter

Measuring water level with ultrasonic sensor.

Arduino water level meter.

Thus the arduino water level indicator helps in preventing wastage of water in overhead tank. 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. 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.

For my next big project automated plant watering system i was in need of having water level meter. Check out the schematic prototype and video below. Project tutorial by newmc. A short message like low normal full or.

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. You can use only the leds if you want the lcd is optional. 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. Download circuit diagram and programming. 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. It is a cheap and intelligent way to control your water tank levels.

This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. The water percentage is calculated and displays in the lcd. Water level meter using the ultrasonic sensor to sense the water level and esp8266 01 to send the data over wifi. Also it can be used for your schoo.

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. The lcd in the receiver unit displays the water level as a long bar. This project is wireless so it is easy to install and it can work up to 100 meters. I was choosing from contact and contactless methods of measuring fluid level in tank.

In this project two circuits are used. The transmitter circuit makes use of an ultrasonic sensor to measure the water. A transmitter circuit and a receiver circuit.
