The overnight comparison of the data from the prototype and the gray wolf system is very encouraging. It looks like the two only had a difference of +or- 15 ppb. Here is the LabView front panel along with the GrayWolf unit showing our measurements that were taken every 5 minutes.
We will begin the same process today for our next set of sensors. While we are waiting on the data to be compiled, we are beginning work on our lesson plan. Specifically, we are working on the engage section of the lesson which will be the into portion of the unit.
Dr. Li gave us the go ahead to begin work on combing all of our sensors, meaning that we have a lot of work to do this afternoon. Here are the begin steps of assembling the new board.
This is our carbon monoxide sensor, notice that it has had some slight modifications made to its connective leads. Since the board is square and the sensor is round, it has caused some mounting issues. Its a lot like trying to put a circular peg into a square hole.
And now with the dust sensor added in the middle.
We finished the day by attending a LabView training in which we designed our own VI(virtual instrument). The topics we discussed will be very helpful when we design our own programs for data acquisition from our sensors. Here is what my VI ended up looking like.
Tomorrow we will test our sensors again and complete more research on professional grade IAQ systems.
