The New Babysense 7 Under Mattress Baby Breathing Movement Monitor

Baby sense is a highly sensitive device that monitors and detects even the smallest breathing movements of the baby through the mattress.
The Original Non-Contact Infant Respiratory Movement Monitor - Now with Improved Sensitivity - Reduced Risk of False Alarms
Babysense sounds an alarm alerting you to check on your baby if no movement is detected within 20 seconds or if the rate of movement slows to less than 10 micromovements per minute.
The passive sensor system is completely safe and has no direct contact with the baby.
Two sensitive sensor pads provide coverage for the entire crib or bed area.
