Smart Temperature Monitoring System with GPS Integration for Pharmaceutical Safety

The Temperature monitoring procedure relies on an Arduino Uno Microcontroller to perform accurate real-time temperature monitoring operations. It is paired with a temperature sensor which operates as a low-cost solution for different environments. The device shows real-time temperature data on an OLED screen that delivers easily read able critical temperature readings through high-contrast display while consuming minimal power. This paper proposes a system which allows users to set custom temperature threshold levels that automatically activate warning alerts when measurements reach those preselected values to boost security applications. A Bluetooth module was integrated into the system to enable smartphone-based data transmission which allows users to monitor temperatures from their mobile phones through an application. This paper demonstrates how Arduino-based systems handle real-time temperature monitoring by providing dependable affordable solutions for temperature monitoring control and remote function control.
