Temperature Data Logger to PC

Temperature program

Temperature program can be used for viewing and saving of several 1-Wire temperature sensors measurements. The interval of the measurements can be adjusted.

Measurements will be shown in day/week/month graphics. These pictures can be saved automatically using defined intervals. Last measurement values can also be saved to html-file. MySQL™ database could also be used for saving the measurements.

Temp program can be localized to other languages very easily. All program captions, messages etc. are read from the external lng-file. Default installation installs english.lng and finnish.lng files to the program directory. Other translations can be done by using the english.lng as a reference file.

If you want to log temperatures with Windows native service, see DS18x Service.

1-wire sensors / chips supported by LogTemp

  • DS1820 temperature sensors
    • Measuring   -60 F- +160F ( -50°C - +70°C)
    • Resolution 0,1°C, accuracy in practice ±0,5°C
    • Better accuracy if calibration is used
  • DS18B20, DS1822 and DS1920 temperature sensors
    • Temperature measurements using type E, J, K, R, S or T thermocouples
  • UV Index Meter
    • Hobby Boards special UV Index Meter with 1-Wire interface
    • Finally this item has been withdrawn from the markets by vendor



This adapter connects single 1-wire devices to USB port.Communication is done thru virtual com port. It is possible to connect every Dallas/Maxim 1-wire device thermometers(DS18B20, DS1820,DS18S20 ....), suitable for 3.3V or 5V operation



The DS18B20 digital thermometer provides 9-bit to 12-bit  temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire® bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.

Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.
