2-Channel Compact USB Temperature and Humidity Logger![]()
TSP01 (1 External TSP-TH TSP-TH (Optional 2nd External ![]() Please Wait
Features
Measuring just 69.5 mm x 12 mm x 20 mm (2.74" x 0.79" x 0.47"), which is approximately the size of a USB thumb drive, the TSP01 provides a very compact solution for measuring temperature and humidity as a function of time via an intuitive software interface. Designed for PC use, it can be plugged into any USB Type A port, and it is capable of measuring and logging up to three different temperature signals (1 internal and 2 external sensors) and one humidity signal (internal sensor) simultaneously. Sensors can be enabled/disabled using the "Settings Panel" within the GUI. ![]() One external TSP-TH NTC thermistor sensor is included with the purchase of the TSP01 temperature and humidity logger, and a second one can be ordered separately. Both probes are directly connected to the USB housing via a 1.5 m long, shielded cable terminated with an headphone connector. The data can be displayed by the included standalone GUI (see the Functionality tab for details). If desired, a user-supplied external NTC thermistor, providing a measurement range of 200 Ω to 80 kΩ, can be wired and used with this temperature and humidity logger. See the image of the 2.5 mm standard stereo headphone connector to the right for the pin connectorization. Thorlabs' Beam Profiler software packages are capable of displaying simultaneously the temperature and humidity data as measured by the TSP01 as well as the beam profile data. When used together, beam profile, temperature, and humidity data is all stored together, thereby providing a complete log of environmental conditions as a function of time during an experiment. The included driver set also allows for integration into third-party software. For driver software, as well as programming reference guides for LabVIEW™, Visual C++, Visual C#, and Visual Basic, please see the Software tab. The TSP-TH thermistor probe is also compatible with the PM400 Touchscreen Power Meter Console.
Functionality Overview of the Software Package![]() Logging:The GUI software has multiple logging options, allowing the user to tailor the software to their preferences. The left section of the interface shows the main measurement options. Measurement Interval: The logging interval, which is the time between two measurements, can be set from 1 to 10,000 seconds in full second increments. Averaging: When averaging is unchecked, a single measured value per selected measurement interval will be logged. By checking this box, all measured values, which are taken every second regardless of the measurement interval chosen, will be averaged over the user-selected measurement interval and a single averaged value will be logged. Logging Control Modes:
The time displayed on the "Graph" and "Table" tabs can be shown in any of the three options mentioned above. As shown in the screenshot above, the "Measurement" tab just shows the value of each active sensor (i.e., no explicit time) and is updated at the user-specified measurement interval that was entered in the logging box. Start / Stop Logging: Results:The logging statistics are summarized in the bottom left box of the GUI screenshot shown above. Display ModesThree different display modes, two of which are shown in the GUI screenshots displayed here, are accessible via tabs. ![]()
Data and Configuration Import/Export: Software for USB Temperature and Humidity LoggerThis software package also includes the instrument drivers for the National Instruments™, LabWindows™/CVI, and LabVIEW™a development environments. The drivers are intended for developers who want to extend or adapt the functionality of the device to their special requirements.
