Nice little sensor, seems to work compared to another slightly more expensive one. Just note that it has "automatic calibration" that is that it comes preset to calibrate it self every 24 hours, that should work fine, provided that there is enough ventilation in the area so that at least at part of every 24 hour period there is clean air. (If you plan to use it in greenhouse or where there is traffic 24 / 7 you will need to turn off the automatic calibration (called ABC)) I am using this with ESP8266 to send the values to Zabbix.
