Vehicle child safety alert system

A passenger detection and safety system comprising:

• seat sensor and an alarm fob;
• wherein the passenger detection and safety system is configured for use with a child safety seat;
• wherein the child safety seat is installed in a vehicle;
• wherein the child safety seat is adapted for use with a passenger;
• wherein the seat sensor is mounted in the child safety seat;
• wherein the seat sensor detects when a passenger is in the child safety seat;
• wherein the alarm fob is carried into the exterior of the vehicle
• wherein if the span of the distance between the seat sensor and the alarm fob is greater than a predetermined maximum allowable distance then the alarm fob generates an audible alarm;
• wherein the seat sensor is designed to detect the body temperature of the passenger;
• wherein the seat sensor comprises a sensor housing, a first GPS module, a first communication module, a first battery, and a temperature sensor;
• wherein the first GPS module, the first communication module, the first battery, and the temperature sensor are contained within the sensor housing;
• wherein the sensor housing is a first rigid case;
• wherein the first GPS module is an electronic device that communicates with the GPS to determine the GPS coordinates of the first GPS module;
• wherein the first communication module is a wireless electronic communication device that allows the seat sensor to communicate with the alarm fob;
• wherein the temperature sensor is measures the temperature of the child safety seat;
• wherein in the temperature sensor is selected from the group consisting of a thermocouple or a thermistor;
• wherein the alarm fob is a handheld device;
• wherein the alarm fob receives messages from the seat sensor and initiates an alarm when the span of the distance between the seat sensor and the alarm fob is greater than the predetermined maximum allowable distance;
• wherein the alarm fob comprises an alarm housing, a second GPS module, a second communication module, a second battery, and a speaker;
• wherein the second GPS module, the second communication module, the second battery, and the speaker are contained within the alarm housing;
• wherein the alarm housing is a second rigid case;
• wherein the alarm housing is formed with an aperture that allows audible sounds to escape the alarm housing;
• wherein the second GPS module is an electronic device that communicates with the GPS to determine the GPS coordinates of the second GPS module;
• wherein the second communication module is a wireless electronic communication device that allows the seat sensor to communicate with the alarm fob;
• wherein the first communication module and the second communication module are matched such that they will communicate with each other;
• wherein the seat sensor further comprises a first logic module;
• wherein the first logic module is a programmable electronic device that manages, regulates, and operates the seat sensor;
• wherein the first logic module is housed in the sensor housing;
• wherein the first GPS module, the first communication module, the first battery, and the temperature sensor are electrically connected to the first logic module;
• wherein the first logic module takes a first action of determining the temperature measured by the temperature sensor;
• wherein the first logic module makes a first decision of whether the temperature sensor is measuring the body temperature of a passenger in the child safety seat;
• wherein the first logic module takes a second action of querying the first GPS module to get the GPS coordinates of the seat sensor;
• wherein the first logic module then takes a third action of sending a first message through the first communication module to the second communication module;
• wherein the first message is a notification that is sent from the first logic module to a second logic module;
• wherein the first message notifies the second logic module of the GPS coordinates of the seat sensor.
