Water Level Sensor Arduino Circuit Diagram

Is an analog output that will be connected to one of the analog inputs on your arduino.

Water level sensor arduino circuit diagram.

In this tutorial we are going to make a simple water level sensor or liquid level detector circuit. Circuit diagram of arduino water level indicator and control using ultrasonic sensor hc sr04r below is the code of the design with the explanation of the codes written inside the as comments. Supplies power for the sensor. In the below diagram water sensor circuit and how it works is broadly highlighted.

Circuit diagram of arduino water level sensor with lcd display program code for serial console this code is for those who don t have lcd or don t want to display characters on this project. The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board. Arduino water level indicator circuit. This code will print the output on the serial console.

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. About water level sensor water level sensor pinout. Here we connect it to analog pin a0. Arduino liquid level sensor circuit.

The water level sensor has 3 pins. In this project two circuits are used. The signal pin s gets connected to an analog pin on the arduino board. Hi sir good afternoon i am trying to interface the water level sensor using arduino nano for harvesting the fish aquarium automatic water level detecting and filling the water below average of water but the tank depth was 45cm the sensor size only the 5 cm how to apply the same application using long height sensor or if any chance to increase the size of sensor please reply this question sir.

When both the legs are dipped in water an electric path is created between the two legs and sensor start conducting current. Basically this is a great piece of code that helps you to learn to use a water level sensor. Transmitter circuit transmitter circuit is shown in the figure below fig1 in this circuit an ultrasonic sensor is connected to pin d9 and d10 pin of arduino. The liquid level sensor board needs about 5v of power.

This circuit measures or detects a required level of water liquid or any fluid. Is a ground connection. The schematic diagram of the arduino liquid level sensor circuit is shown below. The value of conductance current depends on the ratio or level of water.

The circuit diagram is quite simple with only a few components but it can perform a great number of tasks as a monitor for the desired level of any fluid.
