KOHLER touchless faucets with Insight(tm) technology feature an advanced infrared sensor that adapts to its environment. The Insight sensor analyzes the surrounding area and automatically calibrates itself to eliminate false activations and optimize the faucet's performance. And the KOHLER Hybrid energy system offers 30* years of hassle-free power, with no maintenance required. *Just one hybrid energy cell will power a flushometer or faucet for at least 875,000 cycles — no maintenance required. That’s about once every 20 minutes, 24 hours a day, 365 days a year for 30 years.
