Overview
Snuza made the Hero SE as a small wearable that clips to a baby's diaper and senses abdominal movement. If no movement is detected it vibrates first, then sounds an alarm so a parent can check.
Being fully self-contained, it works anywhere without Wi-Fi, apps or cords. It only tracks movement, so it cannot report breathing rate, oxygen or video.
Who it's for
Healthy infants sleeping in their own crib or bassinet are the intended users, including on trips. Parents wanting video, oxygen readings or an app should look at a different monitor.
Pros and cons
- No Wi-Fi, app or cords
- Long battery life
- Vibration before audible alarm
- Movement light and optional tick
- Not a medical device
- Not for co-sleeping
- Clip can shift and cause false alarms
Performance notes
The sensor rests against the belly and detects movement, so correct positioning on the diaper is what prevents false alarms. The staged vibration then alarm gives baby a chance to stir before parents are woken.
