You may have heard the terms “data logging” and “data loggers” but not really be sure of what they are.
A data logger is an electronic instrument that records measurements at set intervals over a period of time. Depending on the particular data logger, such measurements can include:
Air Temperature • Relative Humidity • AC/DC Current and Voltage • Differential Pressure • Time-of-Use (lights, motors, etc.) • Light Intensity • Water Temperature • Dissolved Oxygen • Soil Moisture • Rainfall • Wind Speed and Direction • Leaf Wetness • Pulse Signals • Room Occupancy • Plug Load …and many more!
Data loggers are typically compact, battery-powered devices equipped with an internal microprocessor, data storage, and one or more sensors. For a thorough overview, get the DataLogger Primer By Onset Computer at this link: HERE
