SensAlert by Doona

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 is powered by the Doona app, and uses a cloud-based system to call and send messages, so it does not depend on the phone's signal or status. SensAlert is compatible with most car seats and boosters.

Smart safeguard – a padded insert slips under your child in the car seat and uses Bluetooth plus cloud alerts to notify you if you walk away while they’re still seated.

Multi‑tier alert system – notify → phone call → emergency contacts; the system escalates so caregivers get timely reminders if the first alert is ignored.

Broad compatibility – designed to work with most infant car seats and booster seats, offering peace of mind across different seat brands and setups.
