We started investigating the grey wolf unit to see how it accumulated its data, along with all of the hardware that it involves. The unit consists of a carrying case, grey wolf data collection software, and an air quality probe that connects via USB to any laptop or workstation. We are using an acer netbook as our computer, but the software can be loaded onto any computer. Below you can see the case for the unit, and what the unit is comprised off.
From out tests we found that the unit needs about 10 minutes to warm up before it is ready to start taking readings. We also found that when the unit is attached to the laptop, the computer must not go to sleep mode or the software will stop taking readings.
In comparison, the smaller and less expensive unit that we are trying to build needs 1 to 2 hours to warm up, depending upon the sensor being used. We will be building upon an Arduino board which connects through USB, but also has a wireless component that can be utilized. The analog pins on the board are used for measurement, while the digital must be defined and used for LED. LabVIEW, the program we will be using for coding, has an interface that can be used for programming the Arduino board.
To finish up Day 2 we read through Shahar's research on air quality, and began working our way through some of the LabVIEW tutorials.
