Digital pin 3 of arduino is configured as interrupt pin.
Arduino water meter pulse.
This function then counts the total.
Upload the water flow meter code to the arduino.
Water flow sensor for flow rate volume measurement using arduino code along with.
The code uses an external interrupt on the arduino s digital pin 2.
In some cases newer water meters are equipped with a pulse output.
It emits an infrared light and detects the reflection.
1 whr 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse.
I bought it in 6 dollars.
However if you have an older power meter without a pulse output then you might be able to use one of the options below to sense your water consumption.
This is used to read the pulses coming from the flow meter.
This is used to read the pulses coming from the flow meter.
Flow sensor is powered with an external 9 volt battery.
When the arduino detects the pulse it immediately triggers the pulse counter function.
Reading pulses from meters with pulse outputs.
The code uses an external interrupt on the arduino s digital pin 2.
Use the tcrt5000 ir barrier line track sensor.
Upload the flow meter code to your arduino.
Water flow meter which i used in the project is from aliexpress.
I will explain about it during code explanation.
When the arduino detects the pulse it immediately triggers the pulsecounter function.
For the a100c meter each pulse represents a 1000th of a kwhr of 1whr of energy passing through the meter.
Calculating power 3600 seconds per hour 3600j per pulse ie.
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.
