6. Smart faucets
Smart faucets are relatively cheap and convenient. That’s why they are among the most popular digital gadgets. They are comfortable for kids, the elderly and the disabled.
Smart faucets are hygienic and contamination free: you don’t have to touch the faucet valves (typically they don’t have any). That makes them especially popular for public places. At the same time the technology is environment friendly: it will help you save water and energy.
