The Smart Sleep Sensor

How do I set up the sensor?

Before setting up your sensor, make sure your phone’s Bluetooth is activated. Open the app, tap “More”, choose “Smart Sleep Sensor”, and then “Set up a new sensor”. Then, follow the instructions provided by the app.

When setting up a new replacement sensor, the old sensor will be permanently disconnected and can be discarded appropriately.

How do I use the sensor?

To use the sensor, make sure it is set up and paired with your app (see “How do I set up the sensor?”). Attach the sensor on the dotted line of your Lumi by Pampers diaper. At each change of diaper, peel the sensor off, and place it on the next diaper. The app will notify you when the sensor battery runs low. Keep the sensor clean by wiping it with a damp cloth, baby wipe, or alcohol wipe regularly.

The lights on the back of the sensor are flashing. Is anything wrong?

This is normal; this means the sensor is working. The light level is extremely low and poses no risk.

Can I turn the sensor off?

If the sensor isn’t set up within 30 seconds of being turned on, it will automatically turn off to save battery. Once you’ve set it up, it can no longer be turned off.

How far can the sensor be and still remain connected to my phone?

The sensor uses Bluetooth Low Energy to connect with your phone. BLE connectivity range depends on the construction of your home (distance, materials used, etc.). For most homes, the range should reach to at least the next room.

How long does the battery last? How will I know if the battery is out?

The battery lasts for up to 90 days. To know if the sensor is still working, look for the flashing lights at the back of the sensor. If you see flashing lights, the sensor is still working. If you do not see flashing lights, the battery has run out and it’s time to replace the sensor. Note: Battery is non-replaceable and non-rechargeable. Do not attempt to open the product.

Is it safe to have a connected device on my baby?

Lumi by Pampers™ is completely safe for use with babies. The Lumi sensor features ultra-low energy, meaning that 1 year of use releases less energy than a single 45 second smartphone call.

We applied a rigorous, systematic and scientific evaluation to Lumi, including vetting it with external baby development experts. Lumi passed with flying colors, meeting and often exceeding safety regulations in the USA.

Lumi by Pampers™ is the first and only JPMA certified baby care smart sleep sensor with monitor system that meets their highest standards for safety, performance and functionality.

How do I replace/set up the sensor once the battery has run out?

Set up your new tracker by tapping “More”, then “Diaper Sensor”, and choosing “Set up a new sensor”. You will have to disconnect the current tracker if it is still connected to your app.

Some tips when setting up your new tracker: make sure your phone’s bluetooth is activated. Press and hold the heart icon on the tracker. You’ll see a green blinking light which will become a solid green light. At this point, your tracker is paired and ready to place on your Lumi diaper.

Can the smart sleep sensor store data when it’s not connected to my phone?

Yes, the sensor can store up to 12 hours of data and will update the app once your phone is back in Bluetooth range.

Can the sensor track sleep when my baby’s in a moving apparatus like a stroller or a car?

Not all the time. The sensor tracks sleep using your baby’s movement patterns, so the stroller or car does not enable the sensor to work consistently.
