Calibrating the cheap CO2 sensor

by using the Greenhouse gas Observing SATellite

(GOSAT)

We noticed that we can use that CO2 concentration observation data by GOSAT-2 to know the place with 400ppm concentration of CO2 and calibrate the sensor!

The things we wanted to do is:

• We want to spread the cheap CO2 sensors to many people all over the world that visualize ventilation is enough or not, in the restaurants, offices, and schools
• “Sensor” is cheap, but “Calibration” is expensive
• We need “400ppm CO2 air”
• We want to make it easier to get “400ppm CO2 air”, so that everyone can calibrate cheap CO2 sensors
