> Unlike passive data loggers whose readings can only be retrieved after delivery, reefer cargo condition sensors transmit temperature, relative humidity, CO₂, and ethylene levels continuously in real time to shore-based systems or cloud platforms.

Unlike passive data loggers whose readings can only be retrieved after delivery, reefer cargo condition sensors transmit temperature, relative humidity, CO₂, and ethylene levels continuously in real time to shore-based systems or cloud platforms. Integrated directly into refrigerated containers and reefer trucks, they protect perishable cargo—fruit, seafood, meat, pharmaceuticals—across the entire journey. Shipping lines and cold-chain operators act on the live data stream to adjust container parameters immediately whenever readings move outside the specified range, reducing product loss and avoiding costly cargo claims. The recorded dataset simultaneously serves as regulatory evidence of cold-chain integrity and can be submitted in claims proceedings to establish whether a temperature excursion occurred and at what point in the transit.
