TAMsys Wireless IoT Data Loggers Vs USB-Based Data Loggers

Which scenario do you prefer?


The security cameras record and save the data into the cameras. You go periodically, remove the camera, plug it into your laptop, get data, analyze it and place the camera back after clearing the data.


The security cameras give you a live feed, and the data is recorded directly into the cloud. You don’t need to remove the cameras or do any manual intervention.

Let us guess, you’d prefer scenario#2, right? Correct, what use is it when you know that some incident has happened a week back that you didn’t even realize? You need information in real-time. That is what our wireless data loggers do too.

Welcome to the world of wireless data loggers, the cutting-edge solution for monitoring temperature in the cold chain industry. Wireless data loggers have revolutionized temperature monitoring by providing real-time data collection, analysis, and reporting, ensuring the safety and quality of products throughout their journey in the cold chain.

Here is how wireless data loggers go beyond the traditional USB-based loggers to safeguard the cold chain and mitigate risks associated with temperature excursions.

Wireless data loggers and USB-based data loggers are both valuable tools for temperature monitoring, but they differ in terms of their connectivity, convenience, and data retrieval methods.


  • Wireless IoT data loggers use Wi-Fi, Bluetooth, or cellular networks for wireless connectivity, allowing real-time monitoring and remote access.
  • USB-based data loggers require a direct physical connection to a computer or compatible device via a USB port.


  • Wireless IoT data loggers provide convenience and flexibility, as they can be accessed and monitored from anywhere without needing physical access.
  • USB-based data loggers require a manual connection to a computer for data retrieval and configuration.

Data Retrieval

  • Wireless IoT data loggers transmit data to a centralized system or cloud-based platform, enabling easy and immediate access to temperature information.
  • USB-based data loggers require a physical connection to a computer or device, and data is downloaded using specific PC software provided by the manufacturer.

Power Source

  • Wireless IoT data loggers are typically designed for extremely low power consumption and is battery-powered, offering autonomous operation for extended periods and do not need an external power source for data transfer.
  • USB-based data loggers are also battery powered, but derive power from the connected device such as a PC or a Laptop, while stored data is being extracted.

Real-time Monitoring

  • Wireless IoT data loggers give instant access to temperature data and immediate alerts in the event of temperature excursions. This real-time visibility enables timely interventions to prevent product damage or spoilage.
  • USB-based data loggers provide delayed access and immediate interventions will not be possible

Remote Accessibility

  • Wireless IoT data loggers provide access and monitor remotely from any location as long as the data logger has an internet connection.
  • USB-based data loggers need human intervention to remove the loggers and access the data

Large-scale deployments and scalability

  • Wireless IoT data loggers are extremely valuable for large-scale operations, when monitoring multiple storage facilities or distribution centers, and even complete last-mile delivery networks. This also enables easy scaling with just the need to add devices to the network and power it on.
  • The human intervention takes a longer time to retrieve data and plug them back and this practically makes it impossible for large scale deployment and scaling.

Data Integrity and Security

  • Wireless IoT data loggers eliminate the risks associated with manual data transfer or human error during data entry
  • USB-based data loggers are prone to human errors and has the potential for data loss and manipulation

Alerts and Notifications

  • Wireless IoT data loggers and the accompanying IoT cloud platform generates automated real-time alerts and notifications via email, SMS, or mobile applications in case of temperature deviations or system malfunctions
  • It is not possible to take prompt actions to rectify issues and maintain the integrity of temperature-sensitive products in USB-based data loggers.

Data Analytics and Reporting

  • IoT cloud platform provides advanced data analytics capabilities and reporting features with graphs and trends for temperature data, enabling better insights, compliance monitoring, and quality control
  • USB-based data loggers need to manually create the reports and trends to analyze and make changes


  • Wireless IoT data loggers have strict compliance policies and rules can be monitored, followed and achieved.
  • Compliance deviations will be known only after the data is retrieved manually.

TAMsys wireless IoT data loggers offer real-time monitoring, remote accessibility, convenience, data integrity, scalability, and enhanced analytics compared to USB-based loggers. These benefits make them a powerful and efficient tool for temperature monitoring in the cold chain industry, improving product safety, quality, and regulatory compliance. 

In summary, TAMsys wireless IoT data loggers offer you a viable, reliable and sustainable solution for your business to ensure that your product integrity is safeguarded. Our metrics show that the TAMsys wireless IoT data loggers save over 40% of operational costs and over 80% of user bandwidth compared to manual loggers.

How does it work?

Wireless IoT data loggers work by utilizing cutting-edge semiconductor temperature sensing elements that are inherently precise and extremely power-efficient wireless communication technologies to transmit temperature data from the cold chain. Here are three simple steps of the implementation process for wireless IoT data loggers in the cold chain:

Selection and Placement: We will help you choose wireless IoT data loggers suitable for your specific cold chain requirements, considering factors such as temperature range, accuracy, battery life, and connectivity options (Wi-Fi, Bluetooth, or cellular networks). 

Installation and Configuration: Our team of experts will install the wireless IoT data loggers at strategic locations within the cold chain, such as storage areas, refrigerators, freezers, or transport vehicles. The team will configure the loggers with appropriate settings, such as sampling intervals and alarm thresholds along with the appropriate connectivity infrastructure.

Real-time Monitoring and Alerts: You can now start receiving real-time data, alerts, and reports via email, SMS, WhatsApp or any configuration you need.

It is also advised to periodically maintain and calibrate the wireless IoT data loggers according to your business and compliance needs. This ensures their accuracy and reliability over time.
