Humidity Data Loggers
Humidity data loggers are electronic devices used to measure and record relative humidity, and often temperature, over extended periods of time. They are used in storage areas, museums, archives, laboratories, production environments, building services and for transport and climate monitoring. Continuous acquisition of the microclimate allows detection of limit violations, trend analysis and compliant documentation of environmental conditions.
FAQ
Which parameters do humidity data loggers typically measure?
Humidity data loggers typically measure relative humidity in percent and often temperature in degrees Celsius. Many instruments additionally calculate derived parameters such as dew point or absolute humidity.
What measurement ranges are common for humidity and temperature?
Typical measurement ranges are 0 to 100 % RH for relative humidity and approximately -20 °C to +70 °C for temperature. The usable range depends on the sensor technology and device design.
How accurate are humidity data loggers?
Typical accuracy for relative humidity is in the range of ±1 to ±3 % RH, while temperature accuracy is usually around ±0.3 to ±0.5 °C, depending on the instrument and calibration status.
How often are measurements recorded?
The logging interval can usually be configured freely, for example from a few seconds up to several hours. Shorter intervals provide higher time resolution but require more memory and energy.
How much memory do humidity data loggers provide?
Many devices store several thousand to tens of thousands of readings. For combined temperature and humidity logging, multiple parameters are stored per timestamp. For long-term monitoring, instruments with extended memory or circular logging modes are advantageous.
How is data retrieved from the logger?
Depending on the device, data transfer is via USB, SD card, Ethernet, Wi-Fi or wireless links. Logged data can then be visualized and exported using PC software or web-based applications.
Why is calibration of humidity sensors important?
Humidity sensors are subject to aging and drift. Regular calibration with reference standards or in a climatic chamber ensures that measurements remain within the specified tolerances over time.
How do environmental conditions affect measurement accuracy?
Rapid temperature changes, condensation, dust or chemically aggressive atmospheres may influence the sensor. Appropriate enclosure protection, filters and suitable mounting locations are therefore important for stable measurements.
Where are humidity data loggers typically used?
Typical applications include museum and archive environments, storage and production areas, climate chambers, building services, clean rooms, server rooms, cold-chain monitoring and transport or logistics monitoring.
What is the difference between stand-alone and wireless data loggers?
Stand-alone data loggers store readings locally and are read out periodically. Wireless data loggers transmit measurements continuously or at intervals to a central unit or cloud platform, enabling real-time monitoring and alarm functions.
