Water Sensor Circuit Diagram

It can be used to detect the presence the level the volume and or the absence of water.

Water sensor circuit diagram.

The following circuit shows the water level circuit diagram. The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino. Fig1 in this circuit an ultrasonic sensor is connected to pin d9 and d10 pin of arduino. However one can use two metal needles injection needles to make the sensor.

Arduino water level indicator circuit. Water sensor brick is designed for water detection which can be widely used in sensing rainfall water level and even liquid leakage. Transmitter circuit transmitter circuit is shown in the figure below. Ultrasonic sensor is powered by vcc and gnd pin these pins are connected to vcc and gnd pin of the arduino.

The circuit produces the sound when the sensor senses a drop of a water leak. Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc. In this project two circuits are used. If you are new to arduino and lcds you can consider reading this interfacing arduino and lcd article.

Water level alarm circuit using level sensor. As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism. Arrange the components as shown in the picture. The pic below shows you the pinout of the water flow sensor.

Connect three 1k resistors to the pin 15 13 and 10 of uln 2003 ic as shown in the circuit diagram. We can use the three different colored leds to create three detection levels. Flow sensor photoelectric sensor.
