Key Considerations When Choosing a Data Logger

Cloud Data Hosting, IoT Data Logging or Stand-alone Data Logger

Cloud-based data loggers have gained significant popularity over the past decade. They provide valuable benefits, such as real-time data viewing, but also present challenges related to long-term data retention, data security, and ongoing hosting costs. Additionally, much of this hardware becomes obsolete if you choose to discontinue hosting services.

Modern standalone data loggers address these concerns by offering both cloud hosting capabilities and local data storage as a backup. These IoT data loggers deliver the best of both worlds, combining convenience and reliability.

Classic standalone data loggers can be easier to deploy for short-term or simple applications, or locations with poor communications.

Classic standalone data loggers are often a preferred choice for short-term or straightforward applications due to their simplicity and ease of deployment. They are particularly well-suited for locations with limited or unreliable communication infrastructure, where cloud-based systems may struggle to operate effectively.

These devices typically store data locally, eliminating the need for constant connectivity and reducing dependency on external servers. This makes them an excellent option for remote areas, temporary monitoring projects, or scenarios where cost-efficiency and minimal setup are priorities.

However, while classic standalone loggers excel in these specific use cases, they may lack the advanced features of modern IoT-enabled systems, such as real-time data access and automated alerts. For long-term projects or applications requiring extensive data analysis, integrating them with other technologies or upgrading to hybrid systems that offer both local and cloud capabilities may be a more comprehensive solution.

Identify What You Need to Record with Your Data Logger

Data logging applications vary greatly, yet many rely on similar types of data loggers or software. Key questions to ask include:

Total System Accuracy and Resolution: What You Need to Know

When assessing accuracy, consider the total system accuracy, which includes:

• The data logger itself
• Sensor performance
• Wiring integrity
• Software calculations

More about Accuracy, Resolution and Precision here.

Sampling and Recording

Most smaller data loggers record a single spot reading at a set time interval, typically ranging from seconds to hours for most applications. To ensure good resolution, it’s recommended to oversample by at least fifteen times the rate of change.

More advanced data loggers can perform statistical data analysis on the fly. For example, a logger with a one-second sampling rate and a one-minute recording rate may store 60 readings temporarily, then record their average every minute.

How Will You Manage the Data?

Planning how to retrieve data is crucial. Ensure data is retrieved before the logger’s internal memory fills up.

Data retrieval methods include manual collection via USB, SD cards, or automatic transfers through FTP or email. Alternatively, swapping out the logger with a spare unit for offsite data retrieval is another option.

For setups with multiple sensors or fast sampling rates, large data files may strain software or computer capabilities. As a rule of thumb, record only the data you need and can process effectively.

Mains or Battery Powered?

The choice of power source often depends on the application and location. Small data loggers typically use internal batteries, lasting weeks to years, offering convenience for most situations.

Advanced data loggers with external sensors require more power, often necessitating mains power. When mains power isn’t available, options include balancing performance with power consumption or using solar panels to charge batteries. Alternatively, swapping batteries during data collection can suffice for semi-permanent installations.

Communicating with the Data Logger

• Direct connection via USB or RS232 cable
• LAN or Ethernet network, or Wi-Fi
• 4G/5G cellular data networks
• Satellite communication

Direct communication through USB is common, with manufacturer-provided software handling setup and data retrieval. Configuring a data logger for LAN or Wi-Fi can be more complex and may involve IT policies.

Cellular communication introduces additional challenges, such as firewalls, dynamic IP addresses, and setting up a secure VPN. Sending data via 4G/5G to a server or email is straightforward with a standard data SIM card.

Satellite communication is reserved for remote applications where no other options are viable. Contact us to discuss this in detail.

Software to Complement the Hardware

Different data logger brands offer unique software features. Most basic software supports setup, data retrieval, and visualization in chart or table formats. Data is often exported as CSV, compatible with tools like MS Excel or LibreOffice for further analysis.

Data Logger Calibration

After installation, calibrating the system ensures accuracy across the data logger, sensors, wiring, and software. At a minimum, validate the system with simple checks, such as comparing a thermometer reading to the logger’s temperature sensor.

Time to Find an Expert

Selecting the right data logger requires expertise. Without in-depth product and industry knowledge, recommending the right solution becomes challenging. Ensure your supplier has the technical knowledge to support your needs.

Support is Key

Local after-sales technical support is invaluable. Whether dealing with firmware updates, troubleshooting, or refreshing knowledge, having an experienced, accessible team saves time and money.
