Your Data Acquisition Questions Answered: How to constantly monitor weight changes?



Currently having a project to monitor drainage time. Is this software able to constantly monitor the change in weight along with time? For example once the 1st drop of fitrate enter the beaker on the balance I need the software to record the time start and keep recording for 30 sec.


Yes, if you use the Windmill Logger software it will continually log the change in weight and timestamp each reading. You can keep recording for a set time and start logging when the weight on the balance changes.

Indoor GPS Apps Closer to Reality

GPS usually works well outdoors, but what if you're disoriented in a large building such as a museum or a mall?
