From light waves to quantum physics: the science behind smart washbasins
This article explains the physics behind motion-sensor technology used in modern public washbasins. It uses the concept of light waves to describe how infrared sensors detect presence to trigger automated fixtures.
Why it matters
Understanding the underlying physics of everyday automation demystifies common technology and highlights the practical application of wave theory.
E ven though phones now provide an inexhaustible source of entertainment, going to a nearby movie theatre to watch a film still has its own charm. The shared loud laughter, the annoying phone calls of neighbours, and even the endless paan-masala ads featuring fitness-enthusiastic Bollywood actors remind us of simpler times when only humans were sometimes called intelligent.
