Abstract: Methods, systems and apparatuses to provide life-saving alerts in the event that a child car seat remains occupied under certain unsafe conditions, comprising a software-facilitated means of communication between a short-range radio-enabled sensory device and a mobile device operated by a user. In the event that the sensory device detects that the car child safety seat is occupied and the temperature of the environment has reached or is approaching an unsafe level, the sensory device is operable to send an alert signal to various external devices.
