iconUSB Precision barometer
USB-connected barometer for precise measurement and logging of atmospheric pressure or altitude.
(DISCONTINUED)


Product Description:

Discontinued product. Replaced by: USB-BAR20
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 measured. 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
    • Accuracy: ±0.15 kPa at 25 °C
    • Resolution: 0.0065 kPa (24-bitΔΣ ADC)
  • Internal temperature sensor (typ. -0+3°C at 25°C)
  • Operating temperature: -20°C to +70°C.
  • Enclosure: ABS Plastic, USB-key form factor.

Software:

  • Supported by our free QTenki data logger software.
    • Works under Windows (XP, Win7/8/10 64&32-bit) and Linux.
    • Configurable log file format.
    • Configurable log interval. (from 1 second to one year)
    • Simultaneous use of multiple sensors possible.
  • Can also be used in LabView (Guide here)
