    What is a Data Logger

    A data logger is a device that automatically monitors and records environmental parameters over time, allowing conditions to be measured, documented, analysed and validated. They are typically compact, battery-powered, equipped with an international microprocessor, on-board data storage, and one or more sensors.

    Data loggers can be deployed in a variety of environments to record measurements at set intervals. They can be wired or wireless, and available as single ,stand-alone units or multi-channel systems, recording everything from temperature to humidity and more. The recorded data is stored in the device and can be transferred to a computer for detailed analysis.

    What Data and Measurements Can a Data Logger Collect?

    Depending on the particular data logger, measurements and parameters can include air temperature, 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.

    Common Types of Data Loggers

    Temperature and Humidity Data Loggers

    Temperature and humidity data loggers are commonly used in industries such as pharmaceuticals, agriculture, and HVAC systems. They monitor and record environmental conditions to ensure optimal storage and operation. These data loggers can be wired or wireless, and are essential for maintaining product quality, ensuring compliance with industry standards, and optimising climate control systems.

    Thermocouple Data Loggers

    Thermocouple data loggers measure and record temperature using thermocouple probes, making them ideal for industrial processes, kilns, and high-temperature environments.

    Thermal Data Loggers

    Thermal data loggers track temperature changes over time, providing critical data for processes like food safety, cold chain logistics, and environmental monitoring.

    What are the Key Features of a Data Logger?


    The devices are usually compact and portable for use in the field and in the laboratory.

    Automated Data Collections

    Data can be measured automatically using computer control, meaning there is no need for a physical presence, saving on a valuable resource.

    Easy Data Transfer

    Some data loggers have a handy USB plugin interface or a wireless Bluetooth feature that enables the transfer of data to be even easier and more convenient.

    Remote Accessibility

    The data loggers can be accessed remotely, and readings can be stored to bring back to the laboratory or office after the data has been collected in the field.

    Environmental Durability

    Some data loggers have an IP rating to withstand environmental elements while collecting data.

    365-Day Data Logging

    Data can be collected 365 days a year, 24 hours a day.

    Applications of Data Loggers Include:

    • Environmental Monitoring - to track temperature, humidity, air quality, and light levels in environmental studies, HVAC systems, agriculture, and research projects
    • Industrial Processes - help with monitoring and optimising e.g. pressure, flow rate, voltage, and current
    • Energy Management – help track electricity consumption, solar panel performance, and environmental conditions
    • Research and Development - they assist in areas such as biology, chemistry, physics, and engineering, supporting evidence-based discoveries and innovations

    How Do You Use a Data Logger?

    • Step 1: Download and install software on a mobile device or laptop
    • Step 2: Connect to the data logger and launch parameters
    • Step 3: Place in location and record data for the desired time
    • Step 4: Reconnect to the data logger via mobile device or laptop
    • Step 5: Download data file and readout with analysis software
