Why Data Loggers?
Data loggers are a cost-effective way of logging time-stamped data over time utilising associated instruments and sensors. Data loggers are typically small footprint, battery powered, portable, and are equipped with a microprocessor, internal memory for data storage, and sensors.
Data loggers are normally configured to report on a 24-hour basis for non-critical data and for critical data the reporting frequency can be increased to near real time with the addition of external power supplies or external battery packs.
This allows for a comprehensive, accurate picture of conditions being monitored, such as water flow, water levels, water pressure, water quality, rain fall intensity, wind speed, wind direction, air temperature and relative humidity etc.
Data loggers typically have a sample rate of 1 Hz and can vary from from single-channel input to multi-channel inputs.
