Equipped with precise vibration sensors, on/off status sensors, and temperature/humidity sensors (sensor accessories required), and even with the addition of empty/load monitoring sensors, a real-time wireless sensor network is formed, providing traceable real-time temperature and humidity data monitoring, early warning, and alarm services. This keeps the container’s operation under continuous, 24/7, real-time, and wireless monitoring, thoroughly meeting the regulatory requirements of container companies and resolving safety hazards associated with containerized cargo transportation.
