Data Logger is an electronic instrument that records measurements at set intervals over a period of time.
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, water level, 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
Data loggers are used in a broad range of indoor, outdoor and underwater environments – essentially anywhere data is needed and the convenience of battery power is preferred. The data logger is then reconnected to the computer and the software is used again to read out the data and display the measurements in graphs that show profiles over time
In the case of web-based data logging systems, data are pushed to the Internet for access; with wireless data nodes, data are transmitted to a central receiver; and with Bluetooth Smart loggers, data are downloaded directly to your mobile device.
The four main types of data loggers include stand-alone data loggers, web-based data logging systems, wireless data nodes, and Bluetooth Smart data loggers.
Using the right data logger in handy format, you can always ensure high-precision measurement at one or more measuring locations with an internal or external sensor.
Applications data logging:
• Weather station recording such as wind speed / direction, temperature, relative humidity, solar radiation).
• Hydro graphic recording such as water level, water depth, water flow, water pH, water conductivity.
• Measure variations in light intensity.
• Process monitoring for maintenance and troubleshooting applications.
• Tank level monitoring, Water level monitoring for groundwater studies..
• Record trend data at regular intervals in veterinary vital signs monitoring.
• Temperature, Humidity and Power use for Heating and Air conditioning efficiency studies.
