The code uses an external interrupt on the arduino s digital pin 2.
Arduino water meter pulse.
Upload the water flow meter code to the arduino.
Reading pulses from meters with pulse outputs.
When the arduino detects the pulse it immediately triggers the pulse counter function.
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.
Flow sensor is powered with an external 9 volt battery.
Calculating power 3600 seconds per hour 3600j per pulse ie.
The code uses an external interrupt on the arduino s digital pin 2.
Water flow sensor for flow rate volume measurement using arduino code along with.
This is used to read the pulses coming from the flow meter.
It emits an infrared light and detects the reflection.
Use the tcrt5000 ir barrier line track sensor.
Uploading the flow meter code to the arduino and measuring water flow rate.
In some cases newer water meters are equipped with a pulse output.
In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3.
Digital pin 3 of arduino is configured as interrupt pin.
I will explain about it during code explanation.
For the a100c meter each pulse represents a 1000th of a kwhr of 1whr of energy passing through the meter.
This is used to read the pulses coming from the flow meter.
1 whr 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse.
Water flow meter which i used in the project is from aliexpress.
When the arduino detects the pulse it immediately triggers the pulsecounter function.
This function then counts the total.
Uploading code to arduino and measuring.
