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.
Water flow sensor circuit diagram.
Water flow sensors are installed at the water source or pipes to measure the rate of flow of water and calculate the amount of water flowed through the pipe.
Water flow sensor consists of a plastic valve from which water can pass.
As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism.
Rate of flow of water is measured as liters per hour or cubic meters.
In water flow meter a small fan wings like rotor is placed in way of fluid.
Shaft of this structure has magnetic link with hall s effect sensor.
The connection of the water flow sensor and lcd 16x2 with the arduino is given below in table format.
However one can use two metal needles injection needles to make the sensor.
In our project we connected the water flow sensor to a pipe.
Circuit diagram of water flow meter working of water flow meter using arduino and yf s201.
I used a breadboard and once the connection was done as per the circuit diagram shown above my testing set uplooked something like this.
Water switch circuit schematic.
If you are new to arduino and lcds you can consider reading this interfacing arduino and lcd article.
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.
In my case i connected to gpio2 i e d4.
The sensor works at 5v can be connected to vin of esp8266.
Hence i have not used any external pull up resistors.
The water flow sensor circuit diagram is shown below to interface a water flow sensor and lcd 16x2 with arduino.
It is very simple to measure the water or liquid flow by using water flow sensor yf s201 with arduino this article describes about the water flow sensor and how the water flow sensor works then how to interface water flow sensor with arduino to take control on volume we need to measure water is essential to every thing here this article helps you to built water flow meter to measure the.
Water flow sensor is a digital sensor so we can connect its output pin to any of the digital pins of esp8266.
If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses.
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.
But now let us see the iot water flow meter circuit diagram connection.
When rotor rotates magnetic field cuts the sensor and when it comes in perpendicular electrical.
