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 1-minute 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.

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.

Does it require special diapers?

Yes, the sleep sensor will only work with the Swaddlers for Lumi by Pampers, which are enhanced with a secure attachment zone to keep the sensor in place.
