The Snuza Hero is clipped onto the nappy but there’s a rubberized section that get into contact with the baby to sense movement in their abdomen.
The device is designed to vibrate in an attempt to awaken the baby to begin normal breathing if it tracks weak or abnormal patterns for 15 seconds.
If normal breathing pattern does not begin again after 20 seconds or three vibration attempts, a ticking sound will awake you.
The alarm rings enough to wake you go check on them. The volume options range from low, high and medium. But it has a beep limit even on full volume so you may need a breathing monitor to notify you if you don’t sleep in same bedroom.
You may also set it to tick or emit a green light flashing with every breath. This monitor is smartest to detect missed or shallow heart rate.
On the blinking mode, you only need to sit up on bed or lift your head and look over. The blinking light is visible even through the baby’s pajamas.
