Data loggers are electronic devices that is used to record measurements over a period of time at manipulated interval. These data loggers may be stand-alone, wireless, web-based and Bluetooth.
How do data loggers work?
Typically, data loggers are connected to a computer with the use of a USB. Afterwards, a software, especially for the data logger, is used in manipulating the parameters such as the time to start, the intervals and so on. With this software, the logger will be activated. Then, the data logger is deployed in the intended location; there, it records the data the users need. The storage of these data are in the memory of the data loggers; usually accompanied by date and time as well.
After the set period for monitoring, these data recorders are connected once again to the computer. Using the software, the acquired data is viewed and read out. Measurements in graphs will then show the information over time. Data in tabular form may also be seen as well.
When it comes to web-based data loggers, however, the gathered data are published on the internet for access. And as for wireless data nodes, the gathered data are relayed to a central receiver. Lastly, Bluetooth data loggers’ data can be downloaded directly to mobile devices.
What are data loggers specifically used for?
When we hear the term “data logging” or “data recording”, it seems to always refer to a wide variety of purposes. Oftentimes, these purposes are not specified at all. All we know, from all that we hear, is that data loggers record data for general purposes. But what exactly are these purposes?
Below are the list of applications which data loggers may serve:
- Recording, unattended, the wind’s speed and direction, humidity, temperature, solar radiation
- Recording, unattended, hydrographic such as water depth, water flow, water level, water pH level and water conductivity
- Recording, unattended, the level of soil moisture
- Recording, unattended, pressure of gas
- Counting road traffic
- Measuring temperature of perishable goods for shipments
- Recording environmental conditions for offshore purposes
- Measuring the different variations of the intensity of light
- Process monitoring for verification of conditions of warranty
- Process monitoring for applications of troubleshooting and maintenance
- For research of wildlife using pop-up archive tags
- Measuring handling shock and vibration for distribution packaging
- Measuring the tank level
- Monitoring deformation of objects that have geodetic or geotechnical sensors
- Measuring the environmental conditions, in general
- Monitoring vehicle crashes for vehicle testing purposes
- Monitoring racing of motors and such
- Monitoring the railway signal relay status
- Monitoring data for scientific measurement and investigation especially when concerned about appreciating and acknowledging change
- Recording data trend at intervals for veterinary vital signs
- Recording load profile for management of energy consumption
- Monitoring humidity, temperature and power use for studies concerning efficiency
- Monitoring levels of water for studies concerning groundwater
- For debug and validation of digital electronic bus
Finally, the air is clear as to what exactly these data loggers are for. Of course, people who are in the field of research and monitoring environmental conditions are aware of the services which data loggers offer; however, those who do not belong to that specific data-logging community may have no idea as to what type of data these data loggers actually monitor. Considering the introduction of new data logging technology from growing data acquisition companies, like that of Daqifi’s products for instance, it is, therefore, important to know its specific purposes.
