Different Types Of Data Loggers And Their Critical Applications

Data logging means recording events, observations, or measurements systematically. The device used in data logging is known as a data logger.

Data loggers come into the picture whenever there’s a need to take continuous readings of an instrument.

Significantly used in geotechnical instrumentation and monitoring, data loggers are a necessary device.

Data loggers are classified into different types based on the specific products they test for optimum conditions. Although there are many types of data loggers, temperature data loggers are popular and mostly in use. This article will look at the different types of data loggers and their functions. 

What Is A Data Logger?

Data loggers are electronic devices capable of automatically monitoring and recording environmental parameters over time, allowing conditions to be measured, documented, analysed, and validated. The data logger includes a sensor to receive the information and a computer chip to store it. This stored information in the data logger is then transferred to a computer for analysis.

A data logger is basically an electronic device used to record data over some time. It is used as a built-in device that works in the form of a sensor with the help of either a built-in sensor or an external sensor.

Benefits Of Using A Data Logger

Data loggers are beneficial in collecting and recording data with the help of installed sensors. The data is collected for an assigned duration and specific at predefined intervals, without any manual intervention.

Data logging can also be done manually by constant human observation.

Different Types Of Data Loggers And Their Specific Functions?

Data loggers are used in several applications and are classified into different types based on the specific products they test for optimum conditions. 

Here’s a list of all different types of data loggers used for specific different purposes.

USB Data Loggers

USB data loggers are known to record and store data in an internal memory. The recorded data can be later retrieved on a laptop with the help of a USB cable. This USB is used to charge up the data logger.

WIFI Data Loggers

The web-based data loggers allow remote data retrieval using the Internet, WIFI, or GPRS. 

Wireless Data Loggers

The wireless data logger is compatible to transfer data to the server through Dongle (SIM), LAN, and WIFI. Users can access it from anywhere through the Internet.

Temperature Data Loggers

A temperature data logger is a form of data logger optimized or configured for temperature probes or sensors. You can find some of the best temperature measurement instruments these days, and data loggers act as an excellent companion to them.

Humidity Data Loggers

Humidity Data Loggers are capable to monitor and record both humidity and temperature values over a period of time and can also measure data at defined intervals.

CO2 Data Loggers

The CO2 data logger measures carbon dioxide, temperature, and humidity. The CO2 sensor from the CO2 data logger is separated from the central unit with a connection cable. The observations and readings ​​are displayed on the large display of the CO2 data logger.

What Is The Data Logger Used For?

  • Data loggers are used for several applications, particularly in the geotechnical field. 
  • And also Data logger are used to track and analyse several parameters affecting any structure. Data loggers are associated with the sensors to record data and display it remotely. It is done with respect to specific units, date, time, and battery voltage.
  • Data loggers are used to monitor groundwater levels and rainfall to detect the sources of natural resources.
  • The Data loggers are used in weather stations to monitor different types of climatic factors.
  • And Data loggers track and monitor nuclear power plants to avoid and prevent any fatal accidents like chemical leakages.
  • Also they are also used to monitor tunnel for long-term safety of the tunnel, to study its behaviour over time, especially concerning the rheological behaviour of the rock mass and the changes that take place in some of the fault zones, walled sections, inflow, etc. The data logger sensors continuously capture and store data in its internal memory.
  • Data loggers also monitor the deformation of land surface during excavations. It also works in and around the surrounding areas. When excavation takes place, it induces ground movement, threatening nearby sensitive structures. Hence, data loggers detect any risk assessment and foundation crack at all levels.
