How does a data logger / system based on data logger work?

The data loggers must be programmed to be able to record. This means that the user must provide it with information on how to register. Therefore, a software that can be on a PC or on a mobile, an app, is used to send to the data logger the necessary information on how to perform the recordings. Basically, the main parameter is the rate of acquisition, that is, every how much a recording must be done, for example every second, every 10 seconds, every minute, every 15 minutes and so on. These parameters vary from model to model. Therefore, after having installed the software it is necessary to connect the data logger to the software itself directly or through another device called interface or connection base or reading base (refer to the instructions for your interface to know how to connect the same to the PC and how to connect the logger to the interface). Usually, therefore, the loggers must first be programmed, after being connected to the software, and subsequently started; at the end of the process they are recovered, reconnected and the data downloaded from their memory. Some systems do not require this route because they send data via radio. Therefore, once configured and started they continue to send data to the receiver that stores them in the software.
