CO₂ Gas Sensor
The Go Direct CO2 Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity. It can be used in a variety of biology experiments. It connects via Bluetooth® wireless technology or via USB to your device.
Vernier also has other relatively inexpensive tools.
HydroColor App
HydroColor is a water quality application that uses the smartphone's digital camera to determine the reflectance of natural water bodies. Using this information, HydroColor can estimate water turbidity (0-80 NTU), concentration of suspended particulate matter (SPM) (g/m^3) and the backscattering coefficient in the red (1/m). IMPORTANT: HydroColor requires the use of an 18% photographers gray card as a reference. Gray cards are widely available at photography shops and online. Visit the supporting website for more information on gray cards.

STELLA
The STELLA (Science and Technology Education for Land/Life Assessment) project uses spectrometers that can be built with low-cost components and 3D printed housings to introduce NASA Earth observation technologies and provide authentic hands-on learning experiences for remote sensing education. STELLA instruments help engage students in the quantitative aspects of satellite data, provide insight into the scientific process, and encourage analytical thinking.
