Water Sensor Circuit Diagram

Arrange the components as shown in the picture.

Water sensor circuit diagram.

Transmitter circuit transmitter circuit is shown in the figure below. Connect the pin 7 4 and 2 of uln 2003 ic to create three different levels in the water container. Arduino water level indicator circuit. We can use the three different colored leds to create three detection levels.

Flow sensor photoelectric sensor. The pic below shows you the pinout of the water flow sensor. Water level alarm circuit using level sensor. However one can use two metal needles injection needles to make the sensor.

Water switch circuit schematic. Water sensor brick is designed for water detection which can be widely used in sensing rainfall water level and even liquid leakage. If you are new to arduino and lcds you can consider reading this interfacing arduino and lcd article. As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism.

The circuit produces the sound when the sensor senses a drop of a water leak. It can be used to detect the presence the level the volume and or the absence of water. Ultrasonic sensor is powered by vcc and gnd pin these pins are connected to vcc and gnd pin of the arduino. In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank.

Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc. The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino. The following circuit shows the water level circuit diagram.
