Good sensor, wiring needs care
Accurate data but the pinout diagram could be clearer. Once connected, it is stable.

Perfect for my air quality monitor
Works flawlessly with my ESP32 setup. Readings match my commercial purifier.

Great value
Cheaper than buying a whole unit just for the sensor. Works as expected.
