1. A system for indicating on an electronic device that the refrigerant being introduced in an automobile or vehicle air conditioning system has reached a fully charged fill level, said system comprising:
a sensor, including a main body, electronics operating the sensor, and a temperature sensor spaced approximately 19 mm from the electronics for measuring a real time temperature of air flowing through a vent of the automobile or vehicle air conditioning system, the temperature sensor measuring temperatures in a range of temperatures between minus-20 degrees Fahrenheit (−20° F.) and 150 degrees Fahrenheit (150° F.) with an accuracy variable not exceeding 2 degrees Fahrenheit (2° F.);
a wireless transmitter on said sensor, said wireless transmitter being in communication with the electronic device for wirelessly transmitting said real time temperature to the electronic device;
at least one fastener on said main body, said at least one fastener having a plurality of serrations at a distal end;
said at least one fastener being sized and configured for securing said main body directly on a vane of a vent of the automobile or vehicle air conditioning system, and the vent is set for cold airflow through the vent at its highest setting;
an electronic application configured for use with the electronic device, and the electronic application for use on the electronic device is accessible via a website on the World Wide Web; and
wherein said electronic application is structured and disposed for visually indicating to the user via the electronic device the transmitted real time temperature in real time to the user via the electronic device when the transmitted real time temperature reaches a predetermined value and the amount of refrigerant introduced has reached the fully charged fill level.
