What a data logger is?
A data logger is a device that records data from one or more sensors connected to it in its memory. The data loggers can be of different types: powered by current, battery operated, with manual download, with radio download in real time. Tecnosoft data loggers are generally composed of a processor that manages the reading and archiving of values, one or more sensors, a memory and a battery. In some models the battery is replaceable, even by the user.
