There is just something about having a sensor perform tasks that you could easily do yourself. In this case it is pressing the pump on a soap dispenser. Call us lazy, but the Simple Human Sensor Soap Pump just makes washing your hands that much more interesting.
After placing your hand under the nozzle and receiving a nice drop of soap, the red LED flashes for 20 seconds as a reminder of how long you should lather your hands to ensure a good cleaning.
