Some manufacturers call their faucets “smart faucets” when they mean that the faucet features no-touch operation. These models are also often called touchless faucets. These faucets work with a simple infrared reader like you’d see on a public bathroom sink or a paper towel dispenser. When interrupted by waving your hand, this capacitive field will activate the flow of water for a determined parameter. Some touchless faucets have constant modes, while others have intermittent modes. Most smart faucets with app connectivity also feature an infrared meter for basic touchless operation. “Touchless faucets are ideal for anyone that doesn’t need voice activation but still wants a modern, touchless experience,” says Nicholas Rindt from Kohler. “Touchless faucets like the ones we develop at Kohler can activate in just 20 milliseconds and have an auto shutoff feature.”
