Digital thermometer probe with USB connection, based on DS18B20 1–wire probe and PL-2303TA serial interface, provides 9-bit to 12-bit temperature measurements. Each thermometer has an unique 64-bit serial code stored inside ROM.
Perfect solution for monitoring air temperature at home, in a greenhouse or in a server room. Measurements are more accurate since the probe is not in the same housing as the USB plug. It is also possible to make a probe waterproof by putting it inside a stainless steel tube or put it on longer cable. Desipe probe's wide measuring range it is advisable its usage between –20 and +85 degrees Celsius. Unit of readout value (Celsius or Fahrenheit) depends on software used.
- Measuring range: –55 °C — +125 °C (–67 °F — +257 °F)
- Accuracy: 0.5 °C (0.9 °F) (from –10 °C to +85 °C), 2 °C otherwise
- Resolution: 0.0625 °C (0.1125 °F) at 12-bit
- Data record frequency: above 750 milliseconds
- Cable length (between plug and probe): approximate 82 cm
- Works under Linux™ (Debian, Ubuntu, Openwrt/LEDE etc.) and Windows® XP SP2, Vista, 7, 8, 8.1 and 10. CPU architecture independent: works also on MIPS and ARM.
- Supported by dedicated open source software (released under MIT license) at github.com/usbtemp (C, C++, C# and node.js examples) and wide range of third-party tools and monitoring utilities, e.g. Digitemp, owfs, LogTemp.
