How about temperature accuracy? AirGradient did a bunch of tests and adjustments to mitigate effects of insufficient air circulation and heat from electronics.
On CO2-Sensor Accuracy: Based on AirGradients own research[1], the SCD41 (which Air Lab uses) and SenseAir S8 (which AirGradient uses), compare well indoors. In outdoor environments, the AirGradients sensor is generally better. As the Air Lab is primarily focused on indoor environments, we chose the smaller SCD41 to fit the portable design. But yes, If you're looking for an outdoor air quality monitor, AirGradient will be more accurate.
