Water Sensor Circuit Diagram

Arduino water level indicator circuit.

Water sensor circuit diagram.

Arrange the components as shown in the picture. 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. Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc.

Water level alarm circuit using level sensor. It can be used to detect the presence the level the volume and or the absence of water. Water sensor brick is designed for water detection which can be widely used in sensing rainfall water level and even liquid leakage. The circuit produces the sound when the sensor senses a drop of a water leak.

The pic below shows you the pinout of the water flow sensor. In this project two circuits are used. Transmitter circuit transmitter circuit is shown in the figure below. The following circuit shows the water level circuit diagram.

We can use the three different colored leds to create three detection levels. In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank. As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism. Connect the pin 7 4 and 2 of uln 2003 ic to create three different levels in the water container.

The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino. Connect three 1k resistors to the pin 15 13 and 10 of uln 2003 ic as shown in the circuit diagram. Ultrasonic sensor is powered by vcc and gnd pin these pins are connected to vcc and gnd pin of the arduino.
