A data logger is an instrument that automatically records measurements over time, storing each reading with a time and date stamp.
Depending on the application, data loggers can measure parameters such as temperature, humidity, water level, conductivity, dissolved oxygen, light (PAR), and CO₂ or air quality.
What makes data loggers valuable isn’t just the measurement itself — it’s the continuous, reliable record they create. Instead of a single snapshot, you gain a complete picture of how conditions change over time.
This is why data loggers are widely used across applications where data needs to be trusted, referenced, and acted on, including compliance and audits, environmental monitoring, scientific research, quality assurance, and investigations.
Choosing the right data logger starts with understanding your application — not the product. Rather than comparing models straight away, it’s better to work through a few key questions:
Temperature, humidity, water level, conductivity, CO₂ — each requires different sensors and logger types.
Why it matters:
The parameter you’re measuring determines the type of logger, sensor accuracy, and overall system design.
Is it going:
Why it matters:
The environment determines housing, durability, sealing (IP rating), and long-term reliability.
Why it matters:
This impacts battery life, memory capacity, and whether a reusable or single-use logger is required.
Why it matters:
Different access methods affect cost, convenience, and how quickly you can act on the data.
Not all applications require the same level of precision — or compliance.
In regulated environments, data often needs to be traceable, tamper-evident, and audit-ready, with configuration and reporting aligned to relevant AS/NZS standards.
Why it matters:
Accuracy and compliance requirements directly influence logger selection, setup, and cost – especially where data must stand up to audits or regulatory reporting.
Why it matters:
Many applications don’t need real-time systems — choosing one unnecessarily can add cost and complexity without value.

Data loggers are used across a wide range of industries where understanding environmental conditions, validating processes, or maintaining product quality is critical. While the technology itself is consistent, the way it is applied — and the importance of the data collected — varies significantly depending on the environment and use case.
In environmental and research applications, data loggers are used to support long-term monitoring programs where reliable, time-based data is essential. This includes groundwater and bore monitoring, wetlands and ecosystem studies, catchments and stormwater systems, as well as broader climate and weather monitoring. These projects are typically carried out by environmental consultants, government bodies, councils, universities, and infrastructure developers, where the data collected is often used for compliance, reporting, or scientific analysis. As a result, the focus is not just on capturing data, but on ensuring it is accurate, stable over time, compliance with the EPBC Act (Environment Protection and Biodiversity Conservation Act), and suitable for defensible use in decision-making and reporting.

Water resource monitoring relies on specialised data loggers designed for continuous, often submerged deployment in challenging environments. These systems are used to track groundwater levels in aquifers, monitor rivers and surface water systems, assess stormwater behaviour, and manage water storage assets such as reservoirs. Industries such as water authorities, environmental agencies, civil infrastructure projects, and mining operations depend on this data to support planning, risk management, and regulatory compliance. In these applications, consistency and long-term reliability are critical, as data is often used to identify trends, inform modelling, and support environmental approvals.
Within agriculture and controlled environment settings such as greenhouses, data loggers are used to monitor and optimise growing conditions. This includes tracking temperature, humidity, and microclimates, as well as supporting soil and crop monitoring programs. These tools are widely used across agriculture, horticulture, greenhouse operations, and agronomy research, where even small environmental changes can impact yield and quality. By collecting continuous data over time, growers and researchers can make more informed decisions, improve efficiency, and better manage resources such as water and energy, while also supporting sustainability initiatives.

In buildings and facilities, data loggers are used to monitor environmental conditions over time to support performance, comfort, and system diagnostics. Common applications include indoor air quality monitoring, HVAC performance assessment, and temperature and humidity mapping across spaces. These solutions are used across commercial buildings, healthcare facilities, education campuses, and by facility management teams who need to understand how conditions change over time rather than relying on spot measurements. The data collected helps identify inefficiencies, validate system performance, and support improvements in both occupant comfort and operational efficiency.
In cold chain and logistics applications, data loggers play a critical role in ensuring that temperature-sensitive goods remain within required conditions during storage and transport. This is particularly important in industries such as pharmaceuticals, healthcare, food production, and distribution, where temperature excursions can compromise product quality or safety. Data loggers are used to monitor shipments, validate storage conditions, and provide clear, time-stamped records for audits and compliance purposes. In many cases, particularly for transport, single-use loggers are preferred for their simplicity and ease of deployment, while more advanced solutions may offer real-time tracking for higher-risk or high-value shipments.
Understanding how you access your data is just as important as what you measure. Choosing the right method helps avoid unnecessary cost and complexity, while ensuring you get the level of visibility your application actually requires.

While HOBO is our primary recommendation for environmental and research applications, not every use case requires that level of system or approach.
In applications such as cold chain monitoring, transport validation, or short-term deployment, simpler or more purpose-built solutions are often a better fit.
For example:
Commonly used for shipment monitoring, particularly in pharmaceutical, food, and logistics applications. The range includes single-use loggers for transport validation, as well as real-time options with cloud-based tracking and reporting.
Offers temperature and humidity loggers suited to cold chain, storage, and transport monitoring, including both single-use and reusable devices, with a growing range of real-time solutions.
There are several Australian suppliers and online marketplaces selling data loggers. Here is what sets OneTemp apart for buyers making a considered, compliance-sensitive purchasing decision:
The duration is determined by memory size and the logging interval. Most HOBO loggers store 80,000+ readings, which covers over 270 days at a 5-minute interval. Battery life typically lasts 1 to 3 years.
Most modern loggers use free manufacturer software or smartphone apps, such as HOBOware (desktop) or HOBOconnect (mobile). Some models, such as the Tempmate series, can generate PDF reports automatically upon connection.
Resolution is the smallest change the logger can detect (e.g., 0.02°C), while accuracy is how close that reading is to the actual true value (e.g., ±0.2°C). In critical applications, accuracy is the more vital metric.
Yes. For applications requiring documented traceability (pharma, food safety, research), OneTemp offers NATA-accredited calibration services. Re-calibration is typically recommended every 12 to 24 months.
OneTemp Australia is the sole authorised Australian distributor and recognised calibration service center for HOBO Data Loggers, offering specialised, high-quality calibration in their modern, ISO9001-certified workshop. They provide rapid turnaround, expert technical support, and convenient, comprehensive calibration services.
Battery-powered data loggers are self-contained and require no external power or connectivity; data is retrieved manually via USB or Bluetooth. For remote sites requiring live updates, we offer solar-powered cellular IoT options.
One of the most overlooked aspects of choosing a data logger is how you’ll actually use the data. Here’s what you need to know:
HOBO loggers come with free software that covers 90% of use cases:
If you want centralised monitoring across multiple locations or need real-time visibility, HOBOlink adds:
Need to feed data into Python, Grafana, your own dashboard, or legacy systems?
OneTemp Tip: Before committing to a multi-site deployment, test the included software with a single logger. This helps confirm the workflow matches your team’s needs and skill level.
HACCP typically requires ±0.5°C for most food applications. TGA/pharma cold chain often requires ±0.2°C with documented calibration. OneTemp provides NATA certified calibration services and is an authorised HOBO calibration centre.
The choice comes down to how and when you need access to your data.
USB loggers store data locally and are downloaded manually to a computer. They are the most cost-effective option and are commonly used for compliance reporting where periodic data review is sufficient.
Bluetooth loggers allow wireless data retrieval to a mobile device during site visits, removing the need for cables while still following a manual collection workflow. These are well-suited to laboratories, facilities, and validation work.
Cellular (4G) loggers transmit data automatically to a cloud platform, enabling real-time alerts and continuous visibility across one or multiple sites. These are typically used where immediate response to temperature excursions is required.
Single-use loggers (for example tempmate S2) are designed for single journey tracking with benefits including tamper-evident and auto-generating PDF reports. Multi-use loggers (for example tempmate M2) can be reconfigured for repeated deployments, providing a lower per-use cost over multiple shipments.
Some data loggers have limited memory or battery, such as shipment loggers that often record for only a set number of days. Knowing your desired timeframe and power options ensures your logger is specified correctly and won’t stop mid-process.
Yes, some data loggers can provide alerts, but this depends on how the system is configured.
Traditional loggers that store data locally do not generate alerts, as the data is only reviewed after retrieval.
Wireless or cloud-connected loggers can trigger alerts via SMS or email when predefined thresholds are exceeded, enabling immediate response to critical changes.
For applications where timing is critical, such as cold chain or facility monitoring, a connected logging system is typically required. For audit and validation purposes, standalone loggers remain a reliable and cost-effective option.
A data logger is designed to record, store, and provide a timestamped history of measurements, typically for compliance, validation, or long-term monitoring. Data is either downloaded manually or synced periodically.
An IoT sensor focuses on real-time data transmission and alerts, sending readings continuously to a cloud platform.
While there is some overlap, they serve different purposes:
In many applications, both are used together. For example, a wireless system for alerts, supported by a logger for validated record-keeping.
Calibration frequency and type depends on your application and quality requirements. Customers should check with their relevant quality body or regulatory authority to confirm what is required for their specific environment and use case. Pharma and regulated environments often require annual calibration with NATA-traceable certificates. OneTemp offers local calibration services to meet Australian and New Zealand customer requirements.
Vaccine fridges require loggers that meet National Vaccine Storage Guidelines ‘Strive for 5’, which are typically ±0.5°C accuracy, with min/max recording and alarm indication. HOBO MX series or InTemp CX series are common choices. For TGA compliance, ensure NATA-traceable calibration.
Downloading data from a HOBO data logger depends on the model. Older U-series loggers use HOBOware software (free download for Windows and Mac) to configure and offload data via USB. Note that some U-series models require an optic USB base station and coupler rather than a direct USB cable connection. Newer MX-series models use the HOBOconnect app via Bluetooth, which runs on a phone or tablet with no cables required. Data can be exported to CSV, XLS, or TXT for analysis or compliance records.
Check your logger’s documentation for the specific connection method required.
Standard data loggers typically measure down to -20°C or -40°C, which is not sufficient for ultra-low freezer applications in pharma, biotech, or food storage.
For environments reaching -80°C and below, you need a logger specifically rated for cryogenic conditions. The InTemp CX700 Series Cryogenic Bluetooth Data Loggers, for example, can measure down to -200°C via an external probe.
One important distinction when selecting any logger for this application: the measurement range and the operating range are not the same thing. The probe may be rated to -200°C, but the logger body itself may only be rated to operate at -30°C. This means the logger unit needs to be positioned outside the freezer environment, with only the probe exposed to the ultra-low temperature. Getting this wrong can damage the logger or compromise data accuracy.
Always confirm both specifications before deployment, and check that your setup allows the logger body to remain within its rated operating range.
Data loggers can be used in most environments. Cold storage, underwater, In a dusty facility, outdoors, and mounted up high or remotely are all use cases we’ve seen.
The environment determines how rugged, protected, and specialised your logger needs to be.
Yes, some data loggers can provide alerts, but this depends on how the system is configured.
Traditional loggers that store data locally do not generate alerts, as the data is only reviewed after retrieval.
Wireless or cloud-connected loggers can trigger alerts via SMS or email when predefined thresholds are exceeded, enabling immediate response to critical changes.
