Aiming at monitoring the temperature and humidity inside the refrigerator and managing information of the refrigerator 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 unit and the intelligent cargo identification 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. The system is very powerful to monitor refrigeration unit 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 unit 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.
