What is a Temperature & Humidity data logger?

A temperature and humidity data logger continuously monitors environmental conditions, capturing readings over time to support quality assurance, safety and regulatory compliance.

Where are Temperature & Humidity loggers typically used?

From warehouses and labs to transport, museums and workspaces, these loggers play a crucial role in maintaining stable conditions that preserve product quality, protect equipment, and ensure personnel safety.

How do I access the recorded data?

Accessing your data depends on the type of Lascar data logger you’re using:

  • USB Data Loggers – Simply connect the logger to your PC via USB and use Lascar’s free software to download, view and analyse your recordings.

  • Wi-Fi Data Loggers – Your readings are transmitted automatically to the EasyLog Cloud, where you can view data in real time, generate reports and manage devices from any internet-connected device.

  • Standalone Models with Displays – Some loggers feature built-in LCD screens, allowing you to check readings directly on the device without downloading.

This flexibility makes it easy to review environmental data wherever and however you need it.


Do Temperature & Humidity loggers have alarms?

Yes — many Lascar temperature & humidity data loggers include built-in alarms. These can be configured to alert you when readings go above or below your chosen limits. Depending on the model, alerts may be shown with flashing LEDs, audible beeps, or notifications via the EasyLog Cloud for WiFi-connected devices.
