Arduino Water Level Sensor Circuit

Make an easy water level sensor circuit.

Arduino water level sensor circuit.

For that you can connect the vcc pin on the module to 5v on the arduino and gnd pin to ground. First you need to supply power to the sensor. Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc. It can be used to detect the presence the level the volume and or the absence of water.

This module is designed mainly for the diy hobbyist and provide them a low cost and easy to use water level detection scheme. Water sensor brick is designed for water detection which can be widely used in sensing rainfall water level and even liquid leakage. Simple water level sensor with led. The value of conductance current depends on the ratio or level of water.

As shown in the water level controller circuit given below ultrasonic sensor module s trigger and echo pins are directly connected to pin 10 and 11 of arduino a 16x2 lcd is connected with arduino in 4 bit mode control pin rs rw and en are directly connected to arduino pin 7 gnd and 6. 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 recommended power of the water level sensor is between 3 3v 5v. Analog output will vary depending on the voltage provided to the sensor.

The sensor that i will use for this tutorial can measure water level up to 40mm 4cm. S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. When arduino water level sensor is continuously exposed to. Let s hook the water level sensor up to the arduino.

Wiring water level sensor with arduino. 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. In the below diagram water sensor circuit and how it works is broadly highlighted. In this project two circuits are used.

Circuit diagram and explanation. Vcc pin is the power supply pin for the sensor. When both the legs are dipped in water an electric path is created between the two legs and sensor start conducting current. The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board.

Project tutorial by 123lyt. This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator. In this tutorial you will learn how to use a water level sensor with the arduino uno board. Supplies power for the sensor.
