Water Sensor Circuit Diagram

We can use the three different colored leds to create three detection levels.
Water sensor circuit diagram. Arrange the components as shown in the picture. If you are new to arduino and lcds you can consider reading this interfacing arduino and lcd article. Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc. However one can use two metal needles injection needles to make the sensor.
Transmitter circuit transmitter circuit is shown in the figure below. Water switch circuit schematic. Arduino water level indicator circuit. Ultrasonic sensor is powered by vcc and gnd pin these pins are connected to vcc and gnd pin of the arduino.
The following circuit shows the water level circuit diagram. Fig1 in this circuit an ultrasonic sensor is connected to pin d9 and d10 pin of arduino. The circuit produces the sound when the sensor senses a drop of a water leak. The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino.
Connect the pin 7 4 and 2 of uln 2003 ic to create three different levels in the water container. As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism. In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank. Connect three 1k resistors to the pin 15 13 and 10 of uln 2003 ic as shown in the circuit diagram.
It can be used to detect the presence the level the volume and or the absence of water. Water level alarm circuit using level sensor. Flow sensor photoelectric sensor.
