Product Description:
This USB-connected barometer allows for precise measurement of atmospheric pressure (1 to 120 kPa) or altitude. Thanks to the use of a high resolution ADC (24-bitΔΣ), very small changes in atmospheric pressure can be sensed. If used to compute altitude, variations as small as 10cm can be detected. Designed as a compact USB-Key form factor for easy integration even in space-constrained applications.

Specifications:
  • Atmospheric sensor specs:
    • Range: 1 to 120 kPa (10 to 1200 millibar)
    • Accuracy: ±0.15 kPa at 25 °C (1.5 millibar)
    • Resolution: 0.0065 kPa (0.065 millibar)
  • Internal[1] temperature sensor (typ. -0+3°C at 25°C)
  • Communication: USB
  • Operating temperature: -20°C to +70°C.
  • Enclosure: ABS Plastic, USB-key form factor.
Software:
  • Supported by our free QTenki data logger software.
    • Operates under Windows (XP, Win7/8/10 64&32-bit) and Linux.
    • Configurable log file format and interval as low as one second.
    • Simultaneous use of multiple Dracal sensors supported.
    • Command-line tools included.
  • Can also be used in LabView2 (Guide here)

[1] The internal temperature sensor is used for temperature compensation of the barometric sensor. It has a (non-constant and non-linear) temperature offset and cannot be calibrated, but its reading is available for applications where this is understood and acceptable.
