    FAQS
    ○
    When the Smart Sensor is flat on the floor, what's the distance between the probe and the floor?

    When the Smart Sensor is flat on the floor, about 1mm above the floor. When the water height exceeds this value (the probe will touch the water at this point), the Smart Sensor will detect the water leak.
