Since 2020, Oberhausen has been using our SensorFill. With this, they have upgraded their regular trash cans to smart trash cans! The sensor uses a high-quality laser to accurately determine the fill level regardless of the type of waste. The Sensor Fill has a range of 0 to 4 meters and has an estimated lifespan of 5 to 10 years. With Mr. Fill’s Smart Sensor, any existing trash can becomes smart!
