Water sensors

Hi to all,

I've an aquarium which needs to keep its waterlevel at a minimum level.

Now I need to prepare weekly some osmose water which is kept in waterbox of about 40liters.

I mounted 3 waterlevel sensors, almost at the bottom (absolute waterlevel minimum), in the middle and at the top (absolute waterlevel maximum).

I want a pump (controlled by relay) to start pumping as soon as the waterlevel is below the middle sensor, and stop pumping when the water hits the top sensor.
Then the water may drop until the middle sensor.
This is the sensor : http://www.conrad.be/ce/nl/product/155000/

How do I program this ?

Thanks,
Filip

Hello and welcome

It isn't a sensor, it's just a float switch. So it is acting, will be wired, and coded, exactly like a push button :slight_smile:

May I add that you could have found the exact same switch for less than 2€ on ebay...
