Vacuum Data Logging Dongle

The Bullseye Bluetooth family of gauges have been the go – to gauge for vacuum system maintenance, validation and distillation monitoring.  Since its inception, it has always had the ability to log data to an apple or android based phone or tablet.  It also has the ability through an android device to log data to our cloud service.  Recently we have been getting additional inquiries to create a very simple way for our versatile Bullseye gauge series to log data to a PC.

Use your favorite terminal emulator to connect to the Arrow our Bluetooth dongle, and then you can log and save vacuum data in whatever format your terminal emulator uses.  Attached is what putty logging looks like, and instructions on how to get started.
You can certainly write your driver, or build on this one.  But this is an easy way to get started.


The Arrow  works with the DigiVac Bluetooth Bullseye, Piezo or DASH gauges.
