Smart Garage Door Sensor

Roost's smart garage door sensor lets users know if their garage door is open or closed in case they forgot to close it. The smart door has a built-in accelerometer so users know when the garage door is moving. Roost's smart garage door sensor will be available in the spring for $40. The garage door sensor is less expensive than other smart doors, however, unlike other similar products, this smart garage door can't do more than alert users about their door status.
