What Is a Temperature Data Logger and How Does It Work?

A temperature data logger is a compact electronic instrument that measures temperature at fixed intervals and stores each reading with a time stamp. In cold-chain transport, it travels with the goods and creates an objective history of the conditions experienced between dispatch and receipt. Depending on the model, the record is retrieved as a PDF or CSV file, read through Bluetooth, or transmitted to a cloud platform in near real time.
