The GS502M-C composite air quality module is used to detect PM2.5
The GS502M-C composite air quality module is used to detect PM2.5, carbon dioxide,formaldehyde, temperature and humidity. It outputs the measurements through UART interface. The GS502M-C module has been calibrated in Multi IR’s humidity and temperature controlled facility, so it can be used directly in the testing instruments and monitoring equipment for environment detection.
