Arduino Pulse Counter Water Meter

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.

Arduino pulse counter water meter.

The pulse output may be a flashing led or a switching relay usually solid state or both. A log of all water meter activity is saved on the sd card. Use the tcrt5000 ir barrier line track sensor. Donate to support open hardware.

Best live chat. It emits an infrared light and detects the reflection. Many meters have pulse outputs examples include. In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3.

The ethernet connection is used to answer a handful of basic http requests. In some cases newer water meters are equipped with a pulse output. The home for open source hardware. Water flow meter which i used in the project is from aliexpress.

Digital pin 3 of arduino is configured as interrupt pin. Single phase and three phase electrical energy meters gas meters water meters. I bought it in 6 dollars. The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output.

In the case of an electricity meter a pulse output corresponds to a defined amount of energy passing through the meter kwh. 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 will explain about it during code explanation.
