The kal d06 series digital pulse counter adds a remote digital display with reset to any mechanical water meter with pulse output.
Arduino pulse counter water meter.
The pulse output may be a flashing led or a switching relay usually solid state or both.
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 will explain about it during code explanation.
It emits an infrared light and detects the reflection.
Many meters have pulse outputs examples include.
In some cases newer water meters are equipped with a pulse output.
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.
Single phase and three phase electrical energy meters gas meters water meters.
