This project observes the temperature in a cold storage (once every ten seconds) with the hep of a temperature sensor. A user defined threshold value is set. If the temperature in the cold storage exceeds said threshold value, an led gets lit up and a buzzer goes off, alerting nearby people. Also, an SMS is sent to the user alerting them and informing them of the current temperature.
