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. Flow sensor is powered with an external 9 volt battery. In some cases newer water meters are equipped with a pulse output. In the case of an electricity meter a pulse output corresponds to a defined amount of energy passing through the meter kwh.

In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3. Order online or call toll free 1 800 899 0553. 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. I will explain about it during code explanation.

The home for open source hardware. Water flow meter which i used in the project is from aliexpress. Single phase and three phase electrical energy meters gas meters water meters. A log of all water meter activity is saved on the sd card.

The ethernet connection is used to answer a handful of basic http requests. Use the tcrt5000 ir barrier line track sensor. The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output. I bought it in 6 dollars.

Many meters have pulse outputs examples include. Digital pin 3 of arduino is configured as interrupt pin. It emits an infrared light and detects the reflection.
