Is the SEN0440 MiCS-5524 pre-calibrated for these gases? Also, NO2 is mentioned in the Wiki etc, does this model measure (again, pre-calibrated) NO2?

我们已经在 FireBeetle ESP32 上测试了该传感器,并且 MiCS-5524 与 ESP32 兼容。

请检查以下问题:
1. 传感器工作电压为4.9~5.1V,请确保传感器供电范围在此电压范围内。2
. 请确保EN引脚为低电平,传感器EN引脚悬空或输入高电平将关闭传感器。请将EN连接到GND。

Its library is not working with ESP32-S3. I can read analog value when using simple analogread but when I use "DFRobot_MICS.h" library, all values are always 0.
Can you help me on this?

We have tested this sensor at FireBeetle ESP32 and the MiCS-5524 is ESP32 compatible.

Would you please check the following issues:
1. The sensor operating voltage is 4.9~5.1V, please make sure that the sensor power supply range is within this voltage range.
2. Please make sure the EN pin is low, the sensor EN pin will turn off the sensor if it floats or inputs a high level. Please connect EN to GND.
