Today me and Sundeep collaborated with a goal to successfully perform data acquisitions with the myDAQ, and then to manipulate this data using labview. Sundeep's project requires the use of a solar module with live data acquisition where as mine requires creating resources to teach others how to utilise labview, so it was natural to combine our projects to reach a common goal.
Sundeep:
The goal today was to successfully link a solar module to Labview using the myDAQ. First of all we used the DAQ Assistant in order to get the voltage of the solar module. Due to the fact that I wanted to calculate the energy, I therefore also needed the current since power is equal to voltage*current.
We then created another DAQ Assistant in order to measure the current but then we got stuck since the myDAQ can not handle two DAQ Assistants.
We then decided to ask Chuan and Maria for help and they were more than happy to help us. Their to solution to problem was to use one DAQ Assistant which can measure both voltage and current. The output was then an array which had two values. With the Index Array function in Labview it was then possible to take the individual values out of the array.
After this we multiplied voltage*current to get the power of the solar panel.
On the picture above one can see the front panel of the collaboration so far.
