The purpose of the cargo monitoring system presented in the article during its transportation is to prevent possible emergencies and, as a result, to ensure the operational safety of ships carrying containerized cargo. The paper considers a control system based on a single-chip microcontroller that provides control and processing of information received from temperature, humidity, pressure sensors and a gas analyzer. Data on exceeding the thresholds set for triggering the sensors is transmitted from the monitoring system to the bridge via the ZigBee protocol for low-power wireless networks. The control system also provides, if necessary, the output of an emergency sound and light alarm. The article presents a block diagram of the developed system and a generalized algorithm for its operation. The proposed system can be used in containers of any type.
