This is used to read the pulses coming from the flow meter.
Arduino water meter pulse.
The code uses an external interrupt on the arduino s digital pin 2.
This is used to read the pulses coming from the flow meter.
When the arduino detects the pulse it immediately triggers the pulse counter function.
In some cases newer water meters are equipped with a pulse output.
The code uses an external interrupt on the arduino s digital pin 2.
Uploading code to arduino and measuring.
I bought it in 6 dollars.
Calculating power 3600 seconds per hour 3600j per pulse ie.
Water flow sensor for flow rate volume measurement using arduino code along with.
Water flow meter which i used in the project is from aliexpress.
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.
For the a100c meter each pulse represents a 1000th of a kwhr of 1whr of energy passing through the meter.
This function then counts the total.
Upload the flow meter code to your arduino.
Digital pin 3 of arduino is configured as interrupt pin.
Uploading the flow meter code to the arduino and measuring water flow rate.
Reading pulses from meters with pulse outputs.
Upload the water flow meter code to the arduino.
Flow sensor is powered with an external 9 volt battery.
In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3.
I will explain about it during code explanation.
1 whr 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse.
Use the tcrt5000 ir barrier line track sensor.
