Babysense is a safety device brand specialising in baby movement and breathing monitors designed for peace of mind in infant care. Their flagship products are under‑mattress, non‑contact sensors that detect the baby’s micro‑movements while sleeping. If movement stops for a preset interval—often around 20 seconds—or slows significantly, Babysense triggers an alarm to alert caregivers. Certified as a Class IIb medical device in many regions, Babysense products are used in both home and clinical settings. Key components include dual sensor pads placed beneath the mattress perimeter to cover the full sleeping area, and a central monitor powered by batteries—eliminating cords or wearable parts that could harm the baby. Features often include a volume control, status LEDs, low battery indicators, and simple setup. While highly valued for reducing anxiety around Sudden Infant Death Syndrome (SIDS) or breathing issues, Babysense may be less accurate on memory foam mattresses and requires correct installation for reliable performance.
