Water flow sensor for flow rate volume measurement using arduino code along with.
Flow sensor arduino.
There are only three wires coming from the flow rate sensor.
This project is using arduino microcontroller with hall s effect based water flow sensor yf s201 and lcd is to display output.
Well just take 5 minutes to read the blog and follow the simple 3 rules all your doubts will be gone.
In this tutorial you will learn how to use one water flow sensor with an arduino board the water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor.
We are using the header file of the lcd which eases our interfacing the lcd with arduino and the pins 12 11 5 4 3 9 are allotted for data transfer between lcd and arduino.
In this tutorial we will be hooking up a flow sensor to an arduino uno to measure liquid flow.
I will explain about it during code explanation.
You can find dozens of water flow sensors on our website so the question comes which one is best for your project.
The 5v vcc red wire the gnd black wire and the signal pulse usually yellow line.
Arduino based digital water flow meter using yf s201 hall effect sensor diy water flow meter is an automatic system for measurement of water flow.
In this project we will interface yfs201 hall effect water flow sensor with arduino for measuring flow rate and volume of water or any other liquid this is a very wonderful project that can be used in industry or at home or at water flow measurement application in water tap tunnel river etc.
Just as shown in the schematic diagram the flow sensor is connected with arduino board using jumper wires.
The sensor s output pin is connected with arduino board pin 2.
The explanation of the code is as follows.
In the last blog how to use water flow sensor meter with arduino we explained the basics of the water flow sensor and arduino usage.
When the water flows through the rotor rotor rolls and the speed.
Flow sensor is powered with an external 9 volt battery.
Hall sensor has 3 pins two pins are for power and one pin is for output.
This instructables shows how to build an air flow rate sensor using a low cost differential pressure sensor and readily available materials.
The connections required for this flow rate sensor with respect to the arduino are very minimal.
Its better to power the flow sensor externally since it consumes power which is not suitable to be provided by the arduino power out pins.
This type of flow sensor is designed to measure the volume of liquid traveling past a given point a great way to keep tabs on how much water your drip irrigation system is using or any other project were the flow of liquid needs to be tracked.
After finalization of design the next step is to develop the hardware.
The complete water flow sensor arduino code is given at the bottom of the page.
Digital pin 3 of arduino is configured as interrupt pin.
The design is for an orifice type flow sensor the orifice in our case a washer provides a restriction and.
Connecting the arduino to the flow rate sensor.
