Water Flow Sensor Circuit Diagram

The pic below shows you the pinout of the water flow sensor.

Water flow sensor circuit diagram.

Arduino water flow sensor working. Internally the output pin of the hall effect sensor is pulled high on the circuit board itself as you can see in the breakdown image show above. The circuit diagram for arduino water flow sensor interface is shown in the image below. Flow diagrams are examples of concept diagrams used in many types of risk assessment to assist in identifying and understanding hazards particularly exposures to hazards hazard sources.

The sensor has a magnet and hall effect sensor. In our project we connected the water flow sensor to a pipe. 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.

However one can use two metal needles injection needles to make the sensor. A round shaped magnet is embedded at the center of the turbine and the hall effect sensor is sealed and protected from moisture and placed above the magnet. Flow sensor photoelectric sensor. A water system flow diagram provides a schematic simplified representation of your facility s water distribution system from the water meter or point of entry to the facility to points of use.

The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino. If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses. I used a breadboard and once the connection was done as per the circuit diagram shown above my testing set uplooked something like this.
