Doona SensAlert

SensAlert is the only child car seat alert solution with three levels of alert to keep your child safe, so they're not left unattended in the car. SensAlert detects the presence of a child on board and triggers the alert system when the caregiver moves away from the car (the smartphone loses Bluetooth connection with the SensAlert device). SensAlert uses a cloud-based system to call and send messages, so it does not depend on the phone's signal or status.
