Most electronic sensors, regardless of manufacturer, will interface with the data logger. Some
sensors require external signal conditioning. The performance of some sensors is enhanced with
specialized input modules. The data logger, sometimes with the assistance of various peripheral
devices, can measure or read nearly all electronic sensor output types.
The following list may not be comprehensive. A library of sensor manuals and application notes
is available at
to assist in measuring many sensor types.
