Please note that the X2-5, X16-5, X200-5, X16-1E and B1100 products are not in stock at this time. GCDC can not produce these products due to the supply chain issues of 2022 and the obsolescence of critical semiconductor components. We are in the process of redesigning this product family to use new and improved components. Contact firstname.lastname@example.org for updated status of our product development efforts. In the meantime, please check our other products, such as the HAM logger, or the MEL logger, or the new IMU-GPS logger.
The B1100-2 uses a high precision digital sensor that makes the B1100-2 suitable for altitude measurements, vertical velocity indication, and weather monitoring. Data is recorded at a user selectable rate ranging between 20 Hz to one sample per hour. The B1100-2 can be programmed to start and stop at specific times each day. When connected via the USB to a personal computer, the B1100-2 appears as a standard mass storage device containing the comma delimited data files and user setup files. The commercial standard "AA" battery provides extended life operation suitable to long term data acquisition applications.Buy On Amazon
For more details, specifications, and how to use the B1100-2, please refer to the user manual (.pdf). The user manual includes an example data file and instructions for converting the data and time stamps.
The B1100-2 logger is configured using a simple text file called config.txt located on the microSD card. Below is an example:
;Example B1100-2 config file ;set sample rate sampleperiod = 500 ;set file size to 60 minutes of data samplesperfile = 7200 ;sample temp every 4tth pressure sample ;or every 2 seconds interleave=4 ;set status indicator brightness statusindicators = high ;start when disconnected from PC rebootOnDisconnect ;see B1100-2 user manual for other config options
Data is stored to simple text formatted .csv type files, which are easily imported into any spreadsheet or analysis software (Matlab, Octave, R, etc). Below is a example data file:
