Intelligent Cold Chain Security: Nano Power Temperature Sensors, ESP32 and Telegram Bot Integration for Temperature Assurance and Environmental Harm Prevention

Abstract

The research aims to create a robust cold storage monitoring system for trucks, focusing on parameters like temperature, humidity, and harmful gases. Using nano power temperature, humidity, gas and LDR sensors, the system sets predefined thresholds for each parameter. The MS1089A features energy harvesting and a long battery life. The MS1089A has an I2C interface in addition to other time and power-saving features and it is accurate (±3 °C). By monitoring the temperature and safeguarding the surrounding environment, the nano power temperature sensor is ideal for environmental monitoring. When exceeded or fallen below, automatic notifications with GPS location are sent through Telegram to relevant authorities. Bidirectional communication via a Telegram bot allows users to remotely query sensor values. GPS technology enables live tracking for better cold storage unit management during transportation. The research is scalable, highlighting the potential of IoT in enhancing operational efficiency and reducing risks in cargo transportation. In summary, it integrates wireless sensors, an ESP32 microcontroller and Telegram messaging for a comprehensive cold storage monitoring solution, ensuring the safe transport of temperature-sensitive cargo.
