Sometimes automatic faucet does not respond well to your hands. It makes us feel a little stupid waving our hands back and forth, or the water just stops for no reason.
For this simple hack, all you need is a box cutter and a small piece of cardboard. Laser cutter is optional.
Measure the head of the faucet and make sure the opening fits the faucets head.
Making sure that the bottom part covers the sensor.
