CanAirIO is a citizen science initiative. We are developing a mobile application that is able to set a PM2.5 or CO2 sensors, and other related sensors, as a fixed station using WiFi or mobile station with an smartphone by using a Bluetooth connection.
The Sensirion SCD30 sensor allows for calibration of the sensor to a value other than 400ppm. This is helpful as our outside air is currently around 419ppm, so when you calibrate that to 400, the device always show a too low value.
Additionally, for sensors that don't support this, maybe an offset possibility could be added to allow for corrections if desired. Or even do an offset option for all CO2 sensors and leave the custom calibration for what it is.
