Water Flow Sensor Circuit Diagram
Hence i have not used any external pull up resistors.
Water flow sensor circuit diagram. Flow sensor photoelectric 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. If we take a look at the sides of the water flow sensor we can witness a plastic turbine in the path of water flow. The pic below shows you the pinout of the water flow sensor.
If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses. The sensor has a magnet and hall effect sensor. The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino. The circuit diagram for arduino water flow sensor interface is shown in the image below.
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. In our project we connected the water flow sensor to a pipe. Arduino water flow sensor working. I used a breadboard and once the connection was done as per the circuit diagram shown above my testing set uplooked something like this.
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. 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.
