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.
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.
I bought it in 6 dollars.
Upload the water flow meter code to the arduino.
I will explain about it during code explanation.
Water flow meter which i used in the project is from aliexpress.
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.
Water flow sensor for flow rate volume measurement using arduino code along with.
1 whr 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse.
When the arduino detects the pulse it immediately triggers the pulse counter function.
Upload the flow meter code to your arduino.
Uploading code to arduino and measuring.
When the arduino detects the pulse it immediately triggers the pulsecounter function.
Use the tcrt5000 ir barrier line track sensor.
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.
Digital pin 3 of arduino is configured as interrupt pin.
Uploading the flow meter code to the arduino and measuring water flow rate.
This function then counts the total.
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.
It emits an infrared light and detects the reflection.
