Abstract
A method for calibrating a target gas sensor inside a drone comprises receiving air flow at the target sensor due to least one of diverted propeller air flow or diverted air flow caused by drone flight, measuring a concentration of the target gas, receiving equivalent air flow at a sensor of at least one reference gas having known atmospheric concentration positioned in or on the drone, measuring a concentration of the at least one reference gas, and calibrating the measured concentration of the target gas based on the measured concentration of the at least one reference gas.
