The weight-sensor plate assembly is positioned and configured to detect a weight of a child in a car seat. The weight-sensor plate assembly is in communication with the dashboard sensor including a transceiver. The dashboard or visor sensor is configured to communicate that a child is present within the car seat. The dashboard sensor is in wireless communication with the portable device such as a key fob or smartphone. The dashboard sensor is configured to activate an alarm through the speaker when the portable device extends past a pre-determined proximity range from the dashboard sensor is reached and if the weight of the child is present within the car seat. ## Claims ### Claim 1 A car seat alarm system comprising: a weight-sensor plate assembly; a power source; a dashboard sensor; and a portable device including; a speaker; wherein said weight-sensor plate assembly is positioned and configured to detect a weight of a child in a car seat; wherein said weight-sensor plate assembly is in communication with said dashboard sensor including a transceiver, said dashboard sensor is configured to communicate that said weight of said child is present within said car seat; and wherein said dashboard sensor is in wireless communication with said portable device having a receiver; said dashboard sensor is configured to activate an alarm through said speaker when said portable device extends past a pre-determined proximity range from said dashboard sensor is reached and if said weight of said child is present within said car seat. ### Claim 2 (depends on 1) The car seat alarm system of claim 1, wherein said weight-sensor plate assembly includes a weight-sensor plate within a housing. ### Claim 3 (depends on 2) The car seat alarm system of claim 2, wherein said weight-sensor plate is pressure sensitive. ### Claim 4 (depends on 2) The car seat alarm system of claim 2, wherein said weight-sensor plate assembly is portable and transferable. ### Claim 5 (depends on 4) The car seat alarm system of claim 4, wherein said housing is a cushioned fabric for concealing said weight-sensor plate. ### Claim 6 (depends on 1) The car seat alarm system of claim 1, wherein said weight-sensor plate assembly is in communication with said dashboard sensor via a wireless network (Bluetooth??). ### Claim 7 (depends on 6) The car seat alarm system of claim 6, wherein said dashboard sensor is in wireless communication with said key fob via a wireless network (Bluetooth??). ### Claim 8 (depends on 1) The car seat alarm system of claim 1, wherein said portable device includes a key fob. ### Claim 9 (depends on 8) The car seat alarm system of claim 8, wherein said alarm is deactivated when pressure is removed from said weight-sensor plate assembly. ### Claim 10 (depends on 1) The car seat alarm system of claim 1, wherein said portable device further includes a smartphone. ### Claim 11 (depends on 10) The car seat alarm system of claim 10, is further in communication with a mobile application hosted on said smartphone and configured to provide alerts through said mobile application for viewing on a mobile display. ### Claim 12 (depends on 4) The car seat alarm system of claim 4, wherein said power source is internally housed within said housing. ### Claim 13 (depends on 12) The car seat alarm system of claim 12, wherein said power source is electronically coupled to said weight-sensor plate. ### Claim 14 (depends on 13) The car seat alarm system of claim 13, wherein said weight-sensor plate assembly is substantially planar. ### Claim 15 (depends on 14) The car seat alarm system of claim 14, wherein said weight-sensor plate assembly is positioned underneath said car seat to detect said weight of a child in said car seat. ### Claim 16 (depends on 15) The car seat alarm system of claim 15, wherein said weight-sensor plate assembly comprises a width approximately equal to a width of a seat portion of said car seat. ### Claim 17 (depends on 1) The car seat alarm system of claim 1, wherein said dashboard sensor is mountable within a vehicle. ### Claim 18 (depends on 17) The car seat alarm system of claim 17, wherein said dashboard sensor includes a clip for mounting said dashboard sensor. ### Claim 19 (depends on 1) The car seat alarm system of claim 1, wherein said pre-determined proximity range is greater than 10 feet. ### Claim 20 A car seat alarm system, the car seat alarm system comprising: a weight-sensor plate assembly; a power source; a dashboard sensor; and a portable device including; a speaker; wherein said weight-sensor plate assembly is positioned and configured to detect a weight of a child in a car seat; wherein said weight-sensor plate assembly includes a weight-sensor plate within a housing;
