Everything You Need To Know About Data Loggers

Among a number of highly advanced devices available today, data loggers are certainly one of the most useful electronic devices used these days. You can imagine its utility by reading this article, in which we have tried to compile every minute detail about data loggers. This article attempts to answer each and every query related to data loggers.

What Is A Datalogger?

A data logger is an electronic device used to record data over a period of time now. It is used as a built-in device that works like a sensor via either a built-in sensor/equipment or an external sensor/equipment.

Nowadays, digital data loggers are used on a large scale, as these devices enable automatically monitoring and recording of environmental factors during a specific period. This allows conditions to be measured, recorded, analyzed, and verified.

Usually, data loggers are equipped with a sensor that receives the information and a computer chip that further stores it. This stored information is transferred to further analysis.

What Are Different Types Of Data Loggers?

Data loggers are used in several applications and are classified into different types based on the specific products they test for optimum conditions. Although there are so many types of data loggers, temperature data loggers are popular and mostly in use.

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

  • USB data loggers
  • Wi-Fi data loggers
  • Wireless data loggers
  • Temperature data loggers
  • Humidity data loggers
  • Pressure data loggers
  • CO2 data loggers
  • UV data loggers
  • Shock data loggers
  • Validation data loggers
  • Radio data loggers

What Are Data Loggers Used For, And What Values Can Be Measured With Data Loggers?

Data loggers are used in a variety of applications to monitor and record data of environmental parameters.

  • The data logger is used to monitor farm conditions both on-site and remotely
  • A data logger is used to monitor indoor conditions, temperature measurement, RH, humidity, and also CO2 Levels.
  • A data logger is used to monitor refrigerators from within
  • A data logger is used to monitor the ground water level

How Accurate Are The Measuring Values?

On an average, data loggers work with much better accuracy than other similar devices. Especially digital data loggers are designed in a way that enables them to precisely monitor and record the values.

For instance, a temperature logger can monitor values up to 1-2 degree Fahrenheit. Any data logger give similar accuracy levels depending on the device and measuring factor. 

Data loggers work with a much higher data density as compared to any manual medium, which enables it to provide higher quality data.

How Do Data Loggers Work?

Data loggers automatically collect real-time data from the sensors and display it over the mobile device. They either use a built-in or remote sensor to collect data, a microprocessor to capture and record the data and a built-in memory to store that data. 

Depending on the type of sensors and what kind of signal conditioning is used a data logger can monitor temperature, humidity, pH, pressure, vibration, shock, CO2, voltage, and much more factors.

A data logger operates independently of a computer and many are self-powered so that they can be used remotely continuously logging data even when monitoring goods in transit.

What Is Data Monitoring And Why Is Data Monitoring Important?

Data monitoring is capturing and recording the data in real-time. It reduces costs and facilitates more efficient production processes. It helps in the central monitoring of all audit-relevant parameters and data, It minimises the risks associated and enables prompt intervention in critical instances.

Do Data Loggers Work On A Battery, And What Is The Service Life Of Battery?

The battery life of a data logger depends on a number of parameters including the specific model and sample rate. Generally, the faster the sample rate the shorter the battery life.

Usually, the battery life of a standard high quality data loggers extends from 3years to 8 years depending on their utility and the device they are measuring. 

Advantages Of Using A Data Logger

  • Data loggers effectively and accurately give reliable results as compared to  periodic manual readings
  • Data loggers are best for precise checking of values
  • Data loggers are time saving and cost effective
  • Data loggers allow transmission of data by radio or Wi-Fi


Data loggers record, monitor, and save the collected data efficiently and precisely. They are known for their accuracy, reliability, and faster results. Data loggers relaxes us from the constant checking of temperature and gas exposure in day-to-day work. 

The accuracy of the measurements when the margins are too small to measure, the service life of the rechargeable battery, and data storage has an important role to play for the data loggers to work efficiently.
