The system consists of a diaper with a moisture strip, two reusable activity sensors, and a linked camera that can be used to monitor a baby’s sleeping patterns. Users will also need to purchase Lumi-optimized Swaddler diapers, which come with a more pronounced moisture strip so the sensor can properly assess soiling. In addition to keeping tabs on immediate diaper concerns, the Lumi app uses the Logitech camera to chart sleep and wake times and room temperature.
