Arduino Pulse Counter Water Meter

The ethernet connection is used to answer a handful of basic http requests.
Arduino pulse counter water meter. In some cases newer water meters are equipped with a pulse output. Many meters have pulse outputs examples include. Single phase and three phase electrical energy meters gas meters water meters. 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 home for open source hardware. Flow sensor is powered with an external 9 volt battery. It emits an infrared light and detects the reflection.
In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3. A log of all water meter activity is saved on the sd card. Donate to support open hardware. 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. Best live chat. 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.
The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output. I will explain about it during code explanation. 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.
