Water Sensor Circuit Diagram

In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank.

Water sensor circuit diagram.

Water sensor brick is designed for water detection which can be widely used in sensing rainfall water level and even liquid leakage. Water switch circuit schematic. 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.

Flow sensor photoelectric sensor. Ultrasonic sensor is powered by vcc and gnd pin these pins are connected to vcc and gnd pin of the arduino. Arduino water level indicator circuit. Transmitter circuit transmitter circuit is shown in the figure below.

If you are new to arduino and lcds you can consider reading this interfacing arduino and lcd article. In this project two circuits are used. The circuit produces the sound when the sensor senses a drop of a water leak. Connect the pin 7 4 and 2 of uln 2003 ic to create three different levels in the water container.

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

As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism. It can be used to detect the presence the level the volume and or the absence of water. We can use the three different colored leds to create three detection levels.
