The temperature sensor is located inside a small aluminium case filled with non-inflammable casting resign (VL94). This make the sensor very robust. The size of the sensor is about 40 mm x 25 mm x 15 mm and it is connected to the PC using an USB cable. The product is guarranteed for 2 years.

The measuring resolution is 0.0625° Celsius and the accuracy is at least 1° C. At prduction time the sensor was calibrated to 0.2° C. Using the supplied software the sensor could be recalibrated anytime to get a better result. The valid temperature range for using USB-Temp is -20° to +80° C. Using the sensor outside this range may destroy it.

The temperature is measured with a sensor located on top of the sensor housing, see picture above.

The casting resign protects the sensor against humidity and splash-water. Anyway the sensor must not be operated under water for a long time, because the casting resign will very slowly absorg water. There is no guaranty that the sensor materials will not react with it's environment. The sensor is well protected against mechanical influences.

Up to 127 sensors may theoretically be connected to a PC using several HUBs. This makes it very easy to compare the temperature of different places. When using Cleware USB devices it is not neccessary to install device drivers. The standard USB drivers are sufficient.

To use the USB-Temp the software ClewareControl is available for displaying and managing measured values. The software is running below Windows® Operating Systems (® Microsoft Windows is a registered trademark of the Microsoft Corporation). No special device drivers are neccessary to use the Cleware USB devices.

The application ClewareControl will do the temperature visualisation. Every sensor may control up to 256 actions such as sound, email, execution of any program or switch an USB-Switch.

The USB-Temp may also be controlled via the network. The connection is established with the TCP/IP protocol. On the remote control PC the USB-Temp appears like a local device and could be handled the same way. Several devices even on different PCs could be controlled simultaniously.

The recorded values may automatically be stored on the disk. The compression of the measured values is also supported to reduce memory needs. Export functions to use the data in foreign programs (e.g. Excel) are available.

An Application Program interface (API) to drive the USB-Temp from customer programs is part of the delivery. The API bundles some very simple functions for opening and reading the device. The complex USB device handling is hided.

Linux support is also available. An application program interface (API) and a simple example for accessing an USB-Temp is available.

Every Sensor own its unique serial number. This make it easy to identify the devices when multiple sensors are used the same time.
