“The idea of this project came out when I bought a condensing gas boiler for my apartment. I don’t have any drain close by for the condensed water the boiler produces. So the water is collected in a 20 liter tank (drum) for few days and when it gets filled up, i have to discharge it manually. So I decided to make an Arduino controlled pump which will discharge the water with only one push of the button. A display shows the status of the pump. I’ve added two level sensors to stop the pump if the drain is either overflowing or the level is dropping inside the collecting tank. This is important for the well functioning of the pump, in order to always be submerged.”
