Arduino pulse counter water meter.
The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output.
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.
In some cases newer water meters are equipped with a pulse output.
Using an sd card and an ethernet connection together has proven challenging both use an spi connection until i used the w5100 chip based ethernet shield with an integrated sd card.
I bought it in 6 dollars.
A log of all water meter activity is saved on the sd card.
It emits an infrared light and detects the reflection.
Water flow meter which i used in the project is from aliexpress.
Digital pin 3 of arduino is configured as interrupt pin.
Flow sensor is powered with an external 9 volt battery.

The home for open source hardware.
I will explain about it during code explanation.
In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3.
Single phase and three phase electrical energy meters gas meters water meters.

Use the tcrt5000 ir barrier line track sensor.
In the case of an electricity meter a pulse output corresponds to a defined amount of energy passing through the meter kwh.
