CONSISTS OF A DEVICE WITH AN INFRARED PROXIMITY SENSOR e18-d50nk, WHOSE FUNCTION IS TO PERMIT THE STEP OF WATER, THIS DEVICE WILL APPLY TO THE WASHBASINS AS IN THE SHOPPING CENTERS, WHEN THE HAND IS UNDER THE KEY IT OPENS AND WHEN IT IS REMOVE IT IS CLOSED, BUT IN ADDITION TO THAT, IT IS NEEDED TO MEASURE THE PRESSURE AND FLOW OF WATER THAT GOES OU
