 __NDIR CO<sub>2</sub> Sensor__: Sensor consisted of several components to take CO<sub>2</sub> measurements. They use an infrared (IR) lamp to direct waves of light through a tube filled with the sample air. The air then moves towards the optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. __NDIR CO<sub>2</sub> Sensor__: Sensor consisted of several components to take CO<sub>2</sub> measurements.

 +__Sensors to consider for use__:
 +1) Adafruit MCP9808 QT: Temperature sensor. This sensor gives a high accurate temperature readings as stated on adafruit website the typical accuracy is +/-0.25 Celsius. This to addition to a carbon dioxide sensor could help develop the question and possible answers to how the concentration of carbon dioxide might affect temperature change at different levels of the lower atmosphere. 
 +2) HTU21DF: Humidity & Temperature sensor. This sensor takes measurements of humidity and temperature 
 +3) SHT31: Temperature & Humidity sensor. According to adafruit website, this sensor is more accurate with measurements with an accuracy range of +/-0.25 Celsius. 
 +4) SGP30: MOX Gas Sensor. This sensor would take measurements of eCO<sub>2</sub>, which is an indirect measurement of carbon dioxide, as it is an estimated guess of carbon dioxide.
 +
 +__Ballon considerations__: Changes in temperature in the higher levels of the atmosphere (Radiative cooling), landing (parachute), weight limits (6-12 pounds), wind movement, battery (if it can run as long as needed), method of data trasnmitting (how will we recieve the data), and radiation (could cause overheating).
