Arduino Pulse Counter Water Meter

Water flow meter which i used in the project is from aliexpress.
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. Flow sensor is powered with an external 9 volt battery. Order online or call toll free 1 800 899 0553. It emits an infrared light and detects the reflection.
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. Digital pin 3 of arduino is configured as interrupt pin. The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output. The home for open source 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. 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. Best live chat.
Donate to support open hardware. Single phase and three phase electrical energy meters gas meters water meters. I bought it in 6 dollars. I will explain about it during code explanation.
Many meters have pulse outputs examples include. The pulse output may be a flashing led or a switching relay usually solid state or both. In some cases newer water meters are equipped with a pulse output.
