Arduino Pulse Counter Water Meter

The pulse output may be a flashing led or a switching relay usually solid state or both.

Arduino pulse counter water meter.

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. Order online or call toll free 1 800 899 0553. A log of all water meter activity is saved on the sd card. Water flow meter which i used in the project is from aliexpress.

I bought it in 6 dollars. Donate to support open hardware. 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. The home for open source hardware.

The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output. Use the tcrt5000 ir barrier line track sensor. It emits an infrared light and detects the reflection. I will explain about it during code explanation.

Single phase and three phase electrical energy meters gas meters water meters. In the case of an electricity meter a pulse output corresponds to a defined amount of energy passing through the meter kwh. Digital pin 3 of arduino is configured as interrupt pin. In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3.

Flow sensor is powered with an external 9 volt battery. Many meters have pulse outputs examples include. In some cases newer water meters are equipped with a pulse output.
