Food Product Safety Cap
The following design is intended to cause an alarm if a food product is expired and or has been left out of temperature to long. The audio "beeper" goes of if the food product has been left out of temperature to long.
The light, also as a button, is then pushed when product has been opened, then activating the temperature sensor to alarm , by audio "beeper", when the product has been out of temperature rendering it unsafe to ingest.
The light then is activated by the clock when the "best if used by date" has been reached.
The circuit will cause the temperature sensor to "pop" upward at battery terminal failure indicating "no charge" and status of product unknown..
