Real-time Monitoring and Controlling of Cold Storage Truck using IoT

Electronics Engineering

Refrigerator transportation is an important part of cold chain. Aiming at monitoring the temperature and humidity inside the refrigerator trucks and managing information of the refrigerator trucks internal. In this system, there is a design of an intelligent monitoring system based on the Internet of thing, realized monitoring temperature and humidity inside the refrigerator trucks , and tracking the location of refrigerator trucks real-time in the entire transportation process by using advanced technologies like MQTT, Cloud Computing, sensor technology and the wireless communication technology. The proposed system used an ESP32 as main control unit, DHT22, E18 Infrared sensor, RTC, and GSP module. The system is very powerful to monitor refrigerated truck from anywhere and anytime using mobile application. This system will be capable to do control and monitoring through mobile and web application. We will achieve the good result to data monitoring such as Temperature, humidity, and door status with MQTT. It is satisfied with the performance through the analysis of monitoring system and experiment results for the designed refrigerated truck monitoring system. Moreover, this proposed system has main advantages which are minimize the human effort for the manual monitoring and loss due to uncontrolled environment.
