Úgy tűnik, elég jól működik a trendméréshez, könnyen használható az ESP32 és az esphome segítségével.

Seems to work well enough for trend measurement, easy to use with ESP32 and esphome.

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.

A dobozon kívül dolgozott. Javasoljuk, hogy valaki vásároljon vagy egy kitörési táblát, vagy a készletet egy kitörési táblával. a vezetékek nagyon kicsik, és nehéz volt Dupont csatlakozókat felszerelni.

Worked out of the box. Suggest to someone to purchase either a break out board or the kit with a break out board. the wires are very small and were difficult to put DUPont connectors on.
