How SensorSafe Works
- Chimes through the installed vehicle receiver if child is still secured in the seat when the car is switched off
- Alerts through the caregiver’s cell phone if the child is left behind in the vehicle secured in the car seat and then alerts the designated emergency contact if the situation is still not remedied
- Emergency contact receives GPS coordinates of the vehicle’s last known position
- Alerts through the vehicle receiver and caregiver’s smart phone when the child has unbuckled their chest clip while the vehicle is in motion
- Monitors the back seat temperature to alert through the vehicle receiver and the caregiver’s smart phone when the back seat appears to be too hot or too cold for the child’s comfort
- Provides warnings to the caregiver when the child may have been seated for too long and needs a break
- Receiver plugs directly into your car’s OBD port and syncs with the caregiver’s cell phone
- Only one install needed if receiver is kept plugged into vehicle’s OBD port
- Helps ensure proper use by providing guidance on installation, how-to videos, FAQ’s, direct link to customer service and more through the SensorSafe app
- App can monitor up to 16 chest clips on a single platform
- App download available for Android and IOS
