We devised the Baby Car Seat project to solve the issue of young children left unattended in cars in dangerously hot and cold temperatures, which has resulted in several recent deaths. Our Baby Car Seat uses various sensors to detect if a child is left unattended within the car. We use weight sensors (load cells) for weight detection, microcontrollers, and a 70dB RF module to transmit/receive data. Speakers and liquid crystal displays (LCDs) are used as output components. Switches simulate seat belts closing and opening. Our project operates in two parts, corresponding to child and adult driver. We detect whether the child is seated with the seat belt fastened. Information is transferred to the second Arduino by RF transmitter, from which the driver receives data on the child's location by RF receiver. The output is then displayed on the LCD. If the child is seated but the driver is not, the LCD displays a warning and gives the speaker 2.5 minutes before producing an alarm. If both are seated and the child's seat belt is fastened, indicating that the child has not been left alone in the car, no warning will sound. Our anticipated outcome for the project is to prevent harm or death from freezing or suffocation, due to hot car temperatures in summer and cold temperatures in winter. We hope to perform future upgrades so the system may communicate with multiple phones, send text messages, and even in extreme situations call 911.
